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.

(I deleted the ELF transition kernel warning, it was getting dated..)
- 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.

2) create function usbd_errstr which turns a usbd_status into a sensible

- 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

the time under SMP, but since the bt_cmds() that are sent after other
CPUs are started are not critical, the driver will function until I
can figure out why this is the case.
for as much as one second, but no more. Allows a miscreant to
double-time march the clock, but no worse.
XXX Unlike putting negative deltas in a while(1), performing small
positive steps inside of a while(1) will return EPERM for the
unpermitted ones. Repeated negative deltas are clamped without
error (but the kernel does log a notice).
1 second prior to the highest the clock has run so far. This allows
time adjusters like xntpd to do their work, but the worst a miscreant
can do is "freeze" the clock, not go back in time.
We still need to decide on an algorithm to clamp positive adjustments.
As it stands, it is possible to achieve arbitrary negative adjustments
by "wrapping" time around.

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.

2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.
Change #2 should be committed to -STABLE.
