Bryan Venteicher 32487a8973 Rework when the Tx queue completion interrupt is enabled ...

The Tx interrupt is now kept disabled in the common case, only
enabled when the number of free descriptors in the queue falls
below a threshold. Transmitted frames are cleared from the VQ
before subsequent transmit, or in the watchdog timer.

This was a very big performance improvement for an experimental
Netmap bhyve backend.
