I tried the 2.6.8 3c59x driver (just changed 3c59x.c), problem persists.
I used the Rhine interface (VIA VT6102 Rhine II rev. 78), problem persists.
I removed the bridge and used the Rhine-II interface directly, problem persists.
Apparently the problem is not in 3c59x or bridge code but somewhere
else. Here's a tcpdump of eth3, my Rhine-II interface, again,
192.168.0.1 is the machine running Linux 2.6.9 with the failing amanda
server, 192.168.0.2 is the FreeBSD 4.10-RELEASE-p3 client.

I can provide hex dumps if desired.
