Thanks a lot for your help.  Alas, this does not resolve the issue.
Using tcpdump indicates that receive continues to work while transmit
fails.

I was using gigabit, but the problem persists when I run at 100mbit.
The MTU setting remains at the default 1500 bytes.

In case it's useful, here's the lspci -nv output for my card:
