Hi,
After updating from 7.0-RELEASE to STABLE (around 15/08) my NIC
refuses to handle large file transfers.

When someone tried to copy large (i.e. 700MB) file from samba share
(local gigabit network) or ftp (same LAN),
the NIC was reseted. For a while host was not accesible from the
network, and then it came back with log messages shown above.
I've tried to tune samba socket options (SO_RCVBUF=16384
SO_SNDBUF=16384), and this fixed the problem for samba users. One
interesting thing: copying file to windows XP machine worked fine,
while Vista (SP1 x64) caused the problem.
What solved the problem definitely was disabling TSO for re0 (ifconfig
re0 -tso). I haven't notice any performance drop and it works fine,
but I'm just curious what happened to the 'good' driver from 7.0-RELEASE.
Best regards,
