I've had this thought before, Erik.  I think we've discussed it a bit on past TS sessions.  The big question that I had is whether the Mickrel PHY will support jumbos.  Hardware support isn't universal.  There are also issues with whether the standard consumer Ethernet switches that people are using will support jumbos as well.

It may very well be a non-issue.  It may just be the instrumentation spinning on the blocking IO and running up the counters, but being completely preemptable if something else is happening in the system.

There's also the issue that you don't want the packets to be too big, otherwise latency is going to go up.
