Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

* registers on its DIO bus. The primary registers can be accessed
* using either programmed I/O (inb/outb) or via PCI memory mapping,
* depending on how the card is configured during the PCI probing
* phase. It is even possible to have both PIO and memory mapped
* access turned on at the same time.
*
* Frame reception and transmission with the ThunderLAN chip is done
* using frame 'lists.' A list structure looks more or less like this:
*
* struct tl_frag {
* u_int32_t fragment_address;
* u_int32_t fragment_size;
* };
* struct tl_list {
* u_int32_t forward_pointer;
* u_int16_t cstat;
* u_int16_t frame_size;
* struct tl_frag fragments[10];
* };
*
* The forward pointer in the list header can be either a 0 or the address
* of another list, which allows several lists to be linked together. Each
* list contains up to 10 fragment descriptors. This means the chip allows
* ethernet frames to be broken up into up to 10 chunks for transfer to
* and from the SRAM. Note that the forward pointer and fragment buffer
* addresses are physical memory addresses, not virtual. Note also that
* a single ethernet frame can not span lists: if the host wants to
* transmit a frame and the frame data is split up over more than 10
* buffers, the frame has to collapsed before it can be transmitted.
*
* To receive frames, the driver sets up a number of lists and populates
* the fragment descriptors, then it sends an RX GO command to the chip.
* When a frame is received, the chip will DMA it into the memory regions
* specified by the fragment descriptors and then trigger an RX 'end of
* frame interrupt' when done. The driver may choose to use only one
* fragment per list; this may result is slighltly less efficient use
* of memory in exchange for improving performance.
*
* To transmit frames, the driver again sets up lists and fragment
* descriptors, only this time the buffers contain frame data that
* is to be DMA'ed into the chip instead of out of it. Once the chip
* has transfered the data into its on-board SRAM, it will trigger a
* TX 'end of frame' interrupt. It will also generate an 'end of channel'
* interrupt when it reaches the end of the list.
*/
/*
* Some notes about this driver:
*
* The ThunderLAN chip provides a couple of different ways to organize
* reception, transmission and interrupt handling. The simplest approach
* is to use one list each for transmission and reception. In this mode,
* the ThunderLAN will generate two interrupts for every received frame
* (one RX EOF and one RX EOC) and two for each transmitted frame (one
* TX EOF and one TX EOC). This may make the driver simpler but it hurts
* performance to have to handle so many interrupts.
*
* Initially I wanted to create a circular list of receive buffers so
* that the ThunderLAN chip would think there was an infinitely long
* receive channel and never deliver an RXEOC interrupt. However this
* doesn't work correctly under heavy load: while the manual says the
* chip will trigger an RXEOF interrupt each time a frame is copied into
* memory, you can't count on the chip waiting around for you to acknowledge
* the interrupt before it starts trying to DMA the next frame. The result
* is that the chip might traverse the entire circular list and then wrap
* around before you have a chance to do anything about it. Consequently,
* the receive list is terminated (with a 0 in the forward pointer in the
* last element). Each time an RXEOF interrupt arrives, the used list
* is shifted to the end of the list. This gives the appearance of an
* infinitely large RX chain so long as the driver doesn't fall behind
* the chip and allow all of the lists to be filled up.
*
* If all the lists are filled, the adapter will deliver an RX 'end of
* channel' interrupt when it hits the 0 forward pointer at the end of
* the chain. The RXEOC handler then cleans out the RX chain and resets
* the list head pointer in the ch_parm register and restarts the receiver.
*
* For frame transmission, it is possible to program the ThunderLAN's
* transmit interrupt threshold so that the chip can acknowledge multiple
* lists with only a single TX EOF interrupt. This allows the driver to
* queue several frames in one shot, and only have to handle a total
* two interrupts (one TX EOF and one TX EOC) no matter how many frames
* are transmitted. Frame transmission is done directly out of the
* mbufs passed to the tl_start() routine via the interface send queue.
* The driver simply sets up the fragment descriptors in the transmit
* lists to point to the mbuf data regions and sends a TX GO command.
*
* Note that since the RX and TX lists themselves are always used
* only by the driver, the are malloc()ed once at driver initialization
* time and never free()ed.
*
* Also, in order to remain as platform independent as possible, this
* driver uses memory mapped register access to manipulate the card
* as opposed to programmed I/O. This avoids the use of the inb/outb
* (and related) instructions which are specific to the i386 platform.
*
* Using these techniques, this driver achieves very high performance
* by minimizing the amount of interrupts generated during large
* transfers and by completely avoiding buffer copies. Frame transfer
* to and from the ThunderLAN chip is performed entirely by the chip
* itself thereby reducing the load on the host CPU.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Various updates for the ThunderLAN driver: - When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails, try mapping the other one. Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha. I still have to actually test this in my Alpha box so I'm not going to update /sys/alpha/conf/GENERIC yet.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h.

Overhaul the ThunderLAN driver.

The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused).

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree.

It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree.

It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex.

Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree.

It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

/* Assert the adapter reset bit. */
Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail).

Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha.

Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha. I still have to actually test this in my Alpha box so I'm not going to update /sys/alpha/conf/GENERIC yet.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

/* Set PCI burst size */
Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Various updates for the ThunderLAN driver: - When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails, try mapping the other one. Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha. I still have to actually test this in my Alpha box so I'm not going to update /sys/alpha/conf/GENERIC yet.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work).

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards.

Updates for the ThunderLAN driver: - probe for PHYs by checking the BMSR (phy status) register instead of the vendor ID register. - fix the autonegotiation routine so that it figures out the autonegotiated modes correctly. - add tweaks to support the Olicom OC-2326 now that I've actually had a chance to test one o Olicom appears to encode the ethernet address in the EEPROM in 16-bit chunks in network byte order. If we detect an Olicom card (based on the PCI vendor ID), byte-swap the station address accordingly. XXX The Linux driver does not do this. I find this odd since the README from the Linux driver indicates that patches to support the Olicom cards came from somebody at Olicom; you'd think if anyone would get that right, it'd be them. Regardless, I accepted the word of the disgnoatic program that came bundled with the card as gospel and fixed the attach routine to make the station address match what it says. o The version of the 2326 card that I got for testing is a strange beast: the card does not look like the picture on the box in which it was packed. For one thing, the picture shows what looks like an external NS 83840A PHY, but the actual card doesn't have one. The card has a TNETE100APCM chip, which appears to have not only the usual internal tlan 10Mbps PHY at MII address 32, but also a 10/100 PHY at MII address 0. Curiously, this PHY's vendor and device ID registers always return 0x0000. I suspect that this is a mutant version of the ThunderLAN chip with 100Mbps support. This combination behaves a little strangely and required the following changes: - The internal PHY has to be enabled in tl_softreset(). - The internal PHY doesn't seem to come to life after detecting the 100Mbps PHY unless it's reset twice. - If you want to use 100Mbps modes, you have to isolate the internal PHY. - If you want to use 10Mbps modes, you have to un-isolate the internal PHY. The latter two changes are handled at the end of tl_init(): if the PHY vendor ID is 0x0000 (which should not be possible if we have a real external PHY), then tl_init() forces the internal PHY's BMCR register to the proper values.

Updates for the ThunderLAN driver: - probe for PHYs by checking the BMSR (phy status) register instead of the vendor ID register. - fix the autonegotiation routine so that it figures out the autonegotiated modes correctly. - add tweaks to support the Olicom OC-2326 now that I've actually had a chance to test one o Olicom appears to encode the ethernet address in the EEPROM in 16-bit chunks in network byte order. If we detect an Olicom card (based on the PCI vendor ID), byte-swap the station address accordingly. XXX The Linux driver does not do this. I find this odd since the README from the Linux driver indicates that patches to support the Olicom cards came from somebody at Olicom; you'd think if anyone would get that right, it'd be them. Regardless, I accepted the word of the disgnoatic program that came bundled with the card as gospel and fixed the attach routine to make the station address match what it says. o The version of the 2326 card that I got for testing is a strange beast: the card does not look like the picture on the box in which it was packed. For one thing, the picture shows what looks like an external NS 83840A PHY, but the actual card doesn't have one. The card has a TNETE100APCM chip, which appears to have not only the usual internal tlan 10Mbps PHY at MII address 32, but also a 10/100 PHY at MII address 0. Curiously, this PHY's vendor and device ID registers always return 0x0000. I suspect that this is a mutant version of the ThunderLAN chip with 100Mbps support. This combination behaves a little strangely and required the following changes: - The internal PHY has to be enabled in tl_softreset(). - The internal PHY doesn't seem to come to life after detecting the 100Mbps PHY unless it's reset twice. - If you want to use 100Mbps modes, you have to isolate the internal PHY. - If you want to use 10Mbps modes, you have to un-isolate the internal PHY. The latter two changes are handled at the end of tl_init(): if the PHY vendor ID is 0x0000 (which should not be possible if we have a real external PHY), then tl_init() forces the internal PHY's BMCR register to the proper values.

If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.)

Tweak the Macronix driver to hopefully make it more reliable: - Change to the same transmit scheme as the PNIC driver. - Dynamically set the cache alignment, and set burst size the same as the PNIC driver in mx_init(). - Enable 'store and forward' mode by default. This is the slowest option and it does reduce 100Mbps performance somewhat, but it's the most reliable setting I can find. I'm more interested in having the driver work reliably than trying to squeeze the best performance out of it. The reason I'm doing this is that on *some* systems you may see a lot of transmit underruns (which I can't explain: these are *fast* test systems) and these errors seem to cause unusual and decidedly non-tulip-like behavior. In normal 10Mbps mode, performance is fine (you can easily saturate a 10Mbps link). Also tweak some of the other drivers: - Increase the size of the TX ring for the Winbond, ASIX, VIA Rhine and PNIC drivers. - Set a larger value for ifq_maxlen in the ThunderLAN driver. The setting of TL_TX_LIST_CNT - 1 is too low (the ThunderLAN driver only allocates 20 transmit descriptors, and I don't want to fiddle with that now because the ThunderLAN's descriptor structure is an oddball size compared to the others).

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links.

The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes.

Various updates for the ThunderLAN driver: - When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails, try mapping the other one. Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Various updates for the ThunderLAN driver: - When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails, try mapping the other one. Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha. I still have to actually test this in my Alpha box so I'm not going to update /sys/alpha/conf/GENERIC yet.

Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Small tweak: force another reset of the adapter after probing for all the PHYs in tl_attach(). This is mainly to suck away any possible stray interrupts. This prevents an intermittent problem on some systems where the adapter probes correctly but yields a device timeout (and possible subsequent adapter check) when configured. When I originally tested the driver, I ifconfig'ed the interface after the system had already been booted and didn't notice any problems, but when configuring the interface immediately at startup, it would occasionally timeout and hang, until an adapter check interrupt came along and reset things again. I'm not exactly sure if this is a general problem of just something peculiar to this hardware (there are three devices, including the tlan, all on IRQ 11) but the extra reset shouldn't hurt anything. (It works fine with my 100Mbps Olicom adapter too.) Thanks to Mark Taylor from Cybernet (mtaylor@cybernet.com) for allowing me remote access to a Compaq system for debugging purposes.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards.

tl_softreset(sc, 1);
Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Declare pointers to CSR register space to be volatile. This seems to cure the problems I was having with interrupts not being acknowledged on time. This fixes a problem I observed where starting two ping -f processes at 10Mbps would cause an adapter check due to TX GO commands being issued before TXEOC interrupts were being acked. Also fix a small problem with tl_start(): the mechanism I was using to queue new packets onto the TX chain was bogus. Change adapter check handler so that it resets card state after tl_softreset() is stored. Moved all EEPROM-related macro definitions into if_tlreg.h. Don't allow an autoneg session to start until after the TX queue has been drained, and don't transmit anything until after the autoneg session is complete. Also add support for two more Compaq ThunderLAN-based cards, and three cards from Olicom which also use the ThunderLAN chip. The only thing different about the Olicom cards is that they store the station address at a different location within the EEPROM.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

"Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Remove 2.2.x compatibility code and #ifdefs. Once the shakedown period in -current is over, I'll put a 2.2.x specific version in the RELENG_2_2 branch. If somebody wants a 2.2 version of this driver now, they can check out the previous version from CVS or ask me via e-mail. Gee people, I didn't mean to stir up such a controversy. I just wanted to make sure I could get this thing to work with both kernel versions and didn't want to have to maintain two separate copies. All ya hadda do was ask. :)

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Updates for the ThunderLAN driver: - probe for PHYs by checking the BMSR (phy status) register instead of the vendor ID register. - fix the autonegotiation routine so that it figures out the autonegotiated modes correctly. - add tweaks to support the Olicom OC-2326 now that I've actually had a chance to test one o Olicom appears to encode the ethernet address in the EEPROM in 16-bit chunks in network byte order. If we detect an Olicom card (based on the PCI vendor ID), byte-swap the station address accordingly. XXX The Linux driver does not do this. I find this odd since the README from the Linux driver indicates that patches to support the Olicom cards came from somebody at Olicom; you'd think if anyone would get that right, it'd be them. Regardless, I accepted the word of the disgnoatic program that came bundled with the card as gospel and fixed the attach routine to make the station address match what it says. o The version of the 2326 card that I got for testing is a strange beast: the card does not look like the picture on the box in which it was packed. For one thing, the picture shows what looks like an external NS 83840A PHY, but the actual card doesn't have one. The card has a TNETE100APCM chip, which appears to have not only the usual internal tlan 10Mbps PHY at MII address 32, but also a 10/100 PHY at MII address 0. Curiously, this PHY's vendor and device ID registers always return 0x0000. I suspect that this is a mutant version of the ThunderLAN chip with 100Mbps support. This combination behaves a little strangely and required the following changes: - The internal PHY has to be enabled in tl_softreset(). - The internal PHY doesn't seem to come to life after detecting the 100Mbps PHY unless it's reset twice. - If you want to use 100Mbps modes, you have to isolate the internal PHY. - If you want to use 10Mbps modes, you have to un-isolate the internal PHY. The latter two changes are handled at the end of tl_init(): if the PHY vendor ID is 0x0000 (which should not be possible if we have a real external PHY), then tl_init() forces the internal PHY's BMCR register to the proper values.

Various updates for the ThunderLAN driver: - When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails, try mapping the other one. Apparently, some ThunderLAN parts swap these two registers while others don't. - Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found, program the chip for bitrate mode. This is required for the TNETE110 part, which doesn't have MII support. (It's also obsolete, but there are still some people out there who have them.) With this change and the change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly. (Thanks to Matthew Dodd for getting me one of these cards.) - Convert to bus_space_foo() for register accesses. - Add changes to support FreeBSD/Alpha.

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Convert the ThunderLAN driver to miibus. This took me a while because I had to get the ML 6692 PHY driver working correctly, which is harder than it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no MII support). The ThunderLAN has an internal PHY which makes things a little complicated, but these are the basic rules: - For devices with just the ThunderLAN, the internal PHY is used to provide 10baseT, and 10base5/10baseT support. Autonegotiation will work, but only with 10baseT links. The only thing that really gets negotiated is whether the link is full or half duplex. - For devices with the ThunderLAN and an external 10/100 PHY (like the Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with 100Mbps upgrade daughter card), the external PHY is used for 10baseT and 100baseTX modes. The internal PHY is still used to support 10base5/10base2, though you have to select them manual with ifconfig. - For devices with the ThunderLAN and the ML6692 PHY, both the internal and external PHYs are used, though it will appear as though the 6692 PHY will be used to support 10baseT and 100baseTX modes. In reality, the internal PHY will be used for 10baseT, but this fact will be hidden from the user. The 10base5/10base2 modes can also be selected manually as with above.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh

Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree. This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.

Overhaul the ThunderLAN driver. This update includes the following changes: - Cleaned up register access macros so that they work like the XL driver macros (you can switch from PIO to memory-mapped mode using a single #define -- default is still memory mapped mode). The old 'struct overlayed onto the memory mapped register space' cruft has been removed. - Improved multicast filter code. The ThunderLAN has four entry perfect filter table in addition to the 64-bit hash table: we need one of the perfect filter entries for the station address, but we can use the other three for multicast filtering. We arrange to put the first three multicast group addresses in the perfect filter slots so that commonly joined groups like the all hosts group and the all routers group can be filtered without using up bits in the hash table. Note: in FreeBSD 3.0, multicast groups are stored in a doubly linked list, however new entries are added at the head of the list (thereby pushing existing entries down towards the tail). We want to update the filter starting from the oldest entry to the newest since the all hosts group is always joined first. This means we really want to start from the tail of the list, not the head, but to find the tail we first have to traverse the list all the way to the end and then add entries working backwards. This is a bit of a kludge and could be inefficient if the list is long. - Cleaned up autonegotiation code: tl_autoneg() wasn't always setting modes correctly. - Cleaned up ifmedia update and status routines as well. - Added tl_hardreset() routine to initialize the internal PHY according to the ThunderLAN manual. - Did away with the kludge where PHYs were treated as separate logical interfaces. This didn't really work, especially in the case of the newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which provides only 100Mbps support, relying on the internal PHY for 10Mbps support (both PHYs share the RJ45 port, with the 6692 doing all the autonegotiation work). This kludge resulted from my misunderstanding of the operation of the Compaq Netelligent Dual Port card (the tlan manual mentions multiple channels, but in a different context; this got me a little confused). The driver has been reported to work correctly with the dual port card. - Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully set the ThunderLAN's indirectly accessed internal registers. This makes the EEPROM reading code more reliable. Hopefully I won't have to touch this again before 3.0 goes out the door. I plan to import the 2.2.x version sometime this week. Approved-by: jkh
