Rx/Tx ring diffs

[Simon Josefsson]

I'm seeing the infamous "network hungs on big network load", when
running MPI programs, most notably the NAS Parallel Benchmark.

Using linux 2.1.126 with tulip.c 0.83H and recently started getting
this in my syslog, when shutting down and taking up the network
interfaces.

Does newer relases adress this problem? Is this a hardware problem?

I'll try 0.90 now.

Thanks,
Simon
