MULTIQUEUE won't help on that hardware, only the 82574 has the ability to
use multiple queues in the em driver. Its the advanced server adapters
supported
by the igb driver that are the best choice in that regard.
So, now the driver does not hang but cpu is too high... Anyone else find
this to
be the case that is testing this driver?
