Log Message:
Try to drain the Tx pending queues after dealing with Rx/Tx interrupts.

This fixes a bug whereby a fast cpu with a decent cache can easily
outstrip the GT's ability to put packets on the wire, resulting in a
permanent backlog of mbufs in the Tx pending queues under heavy Tx load.

The bug was masked if the packet buffer was mapped non-cached, which
slowed down the cpu to where it couldn't keep up with the GT at 100mbit.
