I did some more tests with the new driver with 2 machines on a totally 
different segment and the same sorts of packet loss on simple pings.  If I 
revert to the previous version, no packet loss at all.

$FreeBSD: src/sys/dev/fxp/if_fxp.c,v 1.110.2.24 2002/08/09 02:04:20 luigi Exp $
vs
$FreeBSD: src/sys/dev/fxp/if_fxp.c,v 1.110.2.23 2002/07/29 02:50:59 luigi Exp $

I confirmed this on 2 separate machines.


The fxp nics in question are

fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0xa800-0xa81f mem 
0xf9000000-0xf90fffff,0xfd000000-0xfd000fff irq 11 at device 13.0 on pci0
fxp0: Ethernet address 00:a0:c9:89:d5:ba
inphy0: <i82555 10/100 media interface> on miibus0
inphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

and

fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0xa000-0xa03f mem 
0xe9500000-0xe95fffff,0xe9600000-0xe9600fff irq 10 at device 4.0 on pci2
fxp0: Ethernet address 00:d0:b7:db:69:6a
inphy0: <i82555 10/100 media interface> on miibus0
inphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

Both nics on both machines in question do have shard IRQs, but like I said, 
with the previous version of the driver it works fine. If I can provide any 
more information, please let me know. I do have a serial console on one 
machine and will have physical access to it once again on Monday.
