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.

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.
