bug in the stats accounting (nicSendBDs counter was bogus when TX ring was

Update if_tireg.h to look for new firmware fix level.
* Make the network code in the bootstrap more chatty (helps debugging)
* Add nfs root stuff to cpu_rootconf(). I also added a check to make sure
it really was netbooting which allows the use of the same kernel for local
and network boots.
* Tweak the de driver so that it takes the speed setting from the console
for the alpha (some PWSs have broken de chipsets). This is the same
behaviour as NetBSD/alpha.

of the interrupt resource and the final initialisation of the
kernel. Cause of these interrupts is unknown (a resuming device?).
- Try to unbreak what I broke by screwing with the tx queuing again.
I'm waiting for a few more people to test out this code and report back
before I move it into current. Hopefully it will be soon. Basically I
reverted to the old TX queuing strategy.
- Add experimental support for the 3c900B-FL (10mbps ST fiber). The card
should be detected properly and the 10baseFL mode supported, but again
I'm still waiting for word from a tester to see if this actually works.
It shouldn't affect the other cards though; all the differences are in
media selection.
- Set the TX start threshold register to get better performance.
- Increase the size of the RX and TX rings. UDP performance was pretty
bad because the TX ring was too small. Should be substantially better
now (I can saturate the link with either TCP or UDP now).
- Change some of the #defines to reflect proper 3Com ASIC names (boomerang,
cyclone, krakatoa, hurricane).
- Simplify and reorganize interrupt handler; ack all interrupts right
away and then process them. This avoids a potential race condition.
(Noted by Matt Dillon.)
- Reorganize the bridging code to eliminate using a goto to jump into
the middle of an if() {} clause. Sorry, that just made my brain itch.
- Use m_adj() in xl_rxeof().
- Make the payload alignment in xl_newbuf() the default (instead of
just conditionally defined for the alpha) to improve NFS performance
(avoids need for nfs_realign()).
from ever catching up to the transmit consumer index. We can't let this
happen because ti_txeof() depends on the assumption that producer == consumer
means the ring is empty, and producer != consumer means the ring has some
number of active descriptors in it.

Based on code from Hiroki Mori <mori@infocity.co.jp> but reworked by

Add new #ifdef. By defining BKTR_NO_MSP_RESET you can prevent the
MSP34xx being reset by the bt848 driver. This is handy
if you pre-initialise the MSP34xx stereo audio chip in another
operating system first (eg MS Windows).

style pci drivers with a simple one-line change to use a module that
registers itself under new-bus and should in theory enable just about all
of the pci drivers to be loadable (kldload and loader(8)) but without
having the impact of converting the APIs yet.
This also fixes the problem of having undefined variables when only
new-style pci drivers are present.
Convert to new bus and bus dma.
Use latest PCI API.
bt_pci.c:
Fix a few bugs in how resourses are released left over from

Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager. There is further room for optimizing
the interfaces still. All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

just easier to convert the drivers in one go. The changes to the

i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition. eisa, isapnp and pccard* are
not yet using the new resource manager. Once fully converted, all drivers
will be loadable, including PCI and ISA.

transceiver. Note in the manual page that autoselection doesn't
work on the 82c168 because the built-in NWAY support is horribly
broken. Manual mode selection works fine, but autoneg is broken for
everything except maybe 10Mbps half-duplex. There's no simple way
to fix this at the moment, so I have to settle for documenting the
bug for now. Fortunately, there aren't anywhere near as many 82c168
boards around as there are 82c169s.
All it did was match a specific device ID and turn on a quirk for
the wdc driver.
Incidently, at line 1462 there is a return that prevents the generic
ide_pci code from trying to look at the device. I'd be interested
to know if we can take out the return and let the generic code "see" it.
I've left the return in because that's the way it worked before.
(Be sure to rerun config after cvsup or you'll get undefined files!)
perform a cleanup/unifdef sweep over it to tidy things up. The atapi
code is permanently attached to the wd driver and is always probed.
I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.
Remember, this driver is destined to die some time. It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.
ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.
Previously discussed with: sos
- It turns out that the 'promiscuous mode' bug what I discovered with the
PNIC is not restricted to promiscuous mode. I've been doing some remote
debugging for someone with a P75 system, and at 100Mbps, the receiver
screws up even when the NIC is in normal mode. Thus, enable the workaround
for this bug all the time. Note that the workaround is still not enabled
for the PNIC II, since I haven't tested one yet.
- Set the 'arbitration' bit in the bus configuration register and set the
maximum burst size to 16 longwords. This seems to fix problems with
transmit corruption on the P75 system mentioned above. (It probably hurts
performance a bit too, but I've given up trying to make the PNIC perform
well.)
- Rewrite the transmit section to be a little less bogus.
- Set ifq_maxlen correctly. RL_TX_LIST_CNT - 1 is wrong, because for the
RealTek, RL_TX_LIST_CNT is 4. Set it to IFQ_MAXLEN instead.
(cut-down version of the "cyclone" for the small office/home office
"cheap bastard" market). Basically the same as a 3c905B but without
Wake-on-LAN, ROM socket, etc...
- Wait longer for the reset to complete in xl_attach() to try and avoid
'command never completed' warnings.
- Clean up a few odds and ends in xl_attach().
- Add PCI ID for the 3c905B-COMBO (a new card). Right now this is
treated as a 3c905B; I need to dig up one of these cards for testing
before I can make the AUI and BNC ports work.
- Add a hack to force reading the I/O address directly from the PCI
registers if pci_map_port() fails. I SHOULD NOT HAVE TO DO THIS:
SOMEBODY WITH MORE PCI CLUES THAN I SHOULD INVESTIGATE WHY THIS
HAPPENS.

transceiver. Thanks to Brian Walenze for donating a NIC with this chip
on it (LinkSys didn't really sell that many of them and they're not
in production anymore). The driver now distinguishes between the
82c168 and 82c169 when probing. If no MII transceiver is detected,
it switches over to using the internal one.
Oh, I forgot to mention: this driver also works on FreeBSD/alpha (big
thanks to Andrew Gallatin). And there is a 2.2.x version available for
those who stubbornly refuse to upgrade.
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.
Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).
I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.
Like the PNIC, we have to copy packet headers in the receive handler
because the chip will only DMA to longword aligned buffers.
Also do some mindor cleanups.
the alpha. Now the ThunderLAN driver works on the alpha (both my
sample cards check out.) Update the alpha GENERIC config to include
ThunderLAN driver now that I've tested it.
- 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.

This code includes lots of stuff for verbose probing. I'm not 100%
sure that the output of the verbose probe is correct, but everything
else works fine, and -CURRENT was broken for the 5591 before, so I'm
committing it anyway.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.
Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.

a wierd double-queue arrangement.. It always empties the if_snd queue
then puts the transmit packets into a different queue that is limited

This should stop the boot-time XXX warning anyway.
The i++ loop from 1..1000 is too small on very fast machines like
PII 450 MHz. Increasing the loop from 1..100000 lets the machine
access PHY. After this patch it's possible to use a SMC PCI card

was to enable debugging in the driver (#define EPIC_DEBUG 1).

3c905B, the RX and TX reset commands also reset the cyclone chip's internal
PHY, which causes it to restart its autonegotiation session. This takes a
second or two to complete, which makes the interface seem to stop responding
for a few seconds every time you do something that reinitializes it.
Issuing the RX and TX resets on the older 3c905 boomerang adapters doesn't
cause any delay because the boomerang chip requires an external PHY.
This should fix the problem where people doing network installs via 3c905B
cards experience a delay after the interface is first initialized, among
other things.
