Hi Willy,
the current driver version 8.34 includes a new common module, so please
give it a try and let me know.

I've already observed the same behaviour (8.31 though). The problem was
that after sending a few thousands UDP packets, then next UDP packets
would not go out without some TCP traffic to "push" them outside. This
is a real problem on NFS (where I first noticed it). But for me, it
happened only on Yukon cards and not on Yukon2.
Hoping this helps,
Willy
