Log Message:
Changes from FreeBSD:

Implemented a more sophisticated mechanism for handling transmitter
interrupts which now defers them until the transmit queue if filled
up with completed buffers. This has two advantages: first, it reduces
the number of transmitter interrupts to just 1/120th of the rate
that they occured previously, and two, running down many buffers
at once has much improved cache effects.

Defer rundown (m_freem) of completed transmit buffers for no longer
than 1 second.

This brings us up-to-date with the most recent "fxp" driver in FreeBSD.
