It seems igbe never gets an interrupt (as per ether0/ifstats
rintr == 0, rsleep == 1). Pkts received count going up may
have to do with some emulated h/w counter incremented by vbox.
To test this theory I changed code to call igbeinterrupt()
every 4 ticks instead of a real interrupt. In igberproc() I
replaced
sleep(&ctrl->rrendez, igberim, ctlr);
with
tsleep(&up->sleep, return0, 0, 4);
igbeinterrupt(0, edev);
And things seem to be working well enough for '9fs sources'
etc.! Note: this is just a test hack. Ideally interrupt
handling under vbox is fixed up by someone knowledgeable (I
haven't dealt with this stuff in ages).
