I've finished beating the heck out of this driver. Over 12 hours of pounding simultaneously on three NICs in a 2x SMP box running with preempt enabled and not a single oops, BUG(), or deadlock. I'd say the driver is pretty solid at this point; vda's locking patches seem to be safe.
As a sidenote, the max throughput I was able to achieve across three cards was about 1.4 MBytes/sec. A single card could do about 800 KBytes sec; 2 together got to 1.2 MBytes/sec. Heavy CPU utilization the whole way, of course, since these cards do not use DMA.
