Apart from the deadlock bug in 0.92 which can show up under high loads,
Netgear FX310TXs work here under 2.2.17, and essentially saturate a
100Mb/s network on unidirectional tranfers. But this is single
processors, not SMP. ttcp might be useful in testing to eliminate disc
interaction. Or try transfers between /dev/zero and /dev/null perhaps.
