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

/*
|
|
* ThunderLAN adapters typically have a serial EEPROM containing
|
|
* configuration information. The main reason we're interested in
|
|
* it is because it also contains the adapters's station address.
|
|
*
|
|
* Access to the EEPROM is a bit goofy since it is a serial device:
|
|
* you have to do reads and writes one bit at a time. The state of
|
|
* the DATA bit can only change while the CLOCK line is held low.
|
|
* Transactions work basically like this:
|
|
*
|
|
* 1) Send the EEPROM_START sequence to prepare the EEPROM for
|
|
* accepting commands. This pulls the clock high, sets
|
|
* the data bit to 0, enables transmission to the EEPROM,
|
|
* pulls the data bit up to 1, then pulls the clock low.
|
|
* The idea is to do a 0 to 1 transition of the data bit
|
|
* while the clock pin is held high.
|
|
*
|
|
* 2) To write a bit to the EEPROM, set the TXENABLE bit, then
|
|
* set the EDATA bit to send a 1 or clear it to send a 0.
|
|
* Finally, set and then clear ECLOK. Strobing the clock
|
|
* transmits the bit. After 8 bits have been written, the
|
|
* EEPROM should respond with an ACK, which should be read.
|
|
*
|
|
* 3) To read a bit from the EEPROM, clear the TXENABLE bit,
|
|
* then set ECLOK. The bit can then be read by reading EDATA.
|
|
* ECLOCK should then be cleared again. This can be repeated
|
|
* 8 times to read a whole byte, after which the
|
|
*
|
|
* 4) We need to send the address byte to the EEPROM. For this
|
|
* we have to send the write control byte to the EEPROM to
|
|
* tell it to accept data. The byte is 0xA0. The EEPROM should
|
|
* ack this. The address byte can be send after that.
|
|
*
|
|
* 5) Now we have to tell the EEPROM to send us data. For that we
|
|
* have to transmit the read control byte, which is 0xA1. This
|
|
* byte should also be acked. We can then read the data bits
|
|
* from the EEPROM.
|
|
*
|
|
* 6) When we're all finished, send the EEPROM_STOP sequence.
|
|
*
|
|
* Note that we use the ThunderLAN's NetSio register to access the
|
|
* EEPROM, however there is an alternate method. There is a PCI NVRAM
|
|
* register at PCI offset 0xB4 which can also be used with minor changes.
|
|
* The difference is that access to PCI registers via pci_conf_read()
|
|
* and pci_conf_write() is done using programmed I/O, which we want to
|
|
* avoid.
