I have an 82559 card with the same id as the other 8255[78] chips, but
that was made with a date code of 0699 (June 99). The submitter shows
this working with the probe etc, but doesn't actually say it works as
on the ethernet. :-) Assuming it does, this is a RELENG_3 merge candidate.

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.
(Some other changes appear to have snuck in, including a port of Soren's
ATA driver to the Alpha. Soren, back this out if you need to.)
This is a checkpoint of work-in-progress, but is quite functional.
The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

Now should be able to report speed for cards using NatSemi PHY.
(if you have one please let me know if it works as I
only have the Intel version)

const char *. Originally I was going to add casts from const char * to
char * in some of the pci device drivers, but the reality is that the
pci device probes return constant quoted strings.
fxp_stop is called as the first thing in fxp_init, and if the tx desc
list has junk in it, the system may panic. This bug showed up as a side
effect of the changes in rev 1.56, but has been in the code since the
beginning.
interrupts which now defers them until the transmit queue if filled
up with completed buffers. This has two advantages: first, it reduces
the number of transmitter interrupts to just 1/120th of the rate
that they occured previously, and two, running down many buffers
at once has much improved cache effects.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway. Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug. The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

overruns (not that it was a problem, but it could be):
1) Doubled the number of receive buffers in the DMA chain to 64.
2) Do packet receive processing before transmit in the interrupt routine.
if it is in 10Mbps mode and gets certain types of garbage prior to
the packet header. The work-around involves reprogramming the
multicast filter if nothing is received in some number of seconds
(currently set at 15). As a side effect, implemented complete support
for multicasting rather than the previous 'receive all multicasts'
hack, since we now have the ability to program the filter table.
Fixed a serious bug which crept in with the timeout() changes;
the cookie was only saved on the first timeout() call in fxp_init()
and wasn't updated in the most common place in fxp_stats_update()
when the timeout was rescheduled. This bug would have resulted in
an eventual panic if fxp_stop() was called (which happens when any
interface flags are changed, for example).
Fixed a bug in Alpha support that would have caused the TxCB
descriptor chain to span a page boundry, causing serious problems
if the pages didn't happen to be contiguous.
Removed some gratuitous bit masking that was left over from an
older implementation.
Fixed a bug where too much was copied from the configuration
template, spilling over into memory that followed it.
Fixed handling of if_timer...it was cleared too early in some cases.
large enough to contain the ethernet header. There appears to be a
condition where the card can return "0" in some failure cases, and this
causes bad things to happen (a panic).
Fixed a bug in fxp_mdi_write - a hex number was missing a preceding 0x
and this was causing the routine to not wait for a PHY write to complete.
Added support for link0, link1, and link2 flags to toggle auto-
negotiation, 10/100, and half/full duplex:
link0 disable auto-negotiation
When set, these flags then have meaning:
-link1 10Mbps
link1 100Mbps
-link2 half duplex
link2 full duplex
...needs a manual page.
written:
1) Full duplex mode is now supported (and works!)
2) The 10Mbps-only PCI Pro/10 should now work (untested, however)
Thanks to Justin Gibbs for providing a PCI bus analyzer trace while the
Intel Windows driver was configuring the board...this made it possible
to figure out the mystery bit that I wasn't setting in the PHY for full
duplex to work.
Disabled the DMA byte counters - I had it this way originally and this is
the recommended setting.
Set crscdt to CRS only (0) since this is what it should be for an MII PHY.
Also fixed some comments.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
previous hackery involving struct in_ifaddr and arpcom. Get rid of the
abominable multi_kludge. Update all network interfaces to use the
new machanism. Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).
