forcedeth: new backoff implementation

This patch adds support for a new backoff algorithm for half duplex supported
in newer hardware.  The old method is will be designated as legacy mode.

Re-seeding random values for the backoff algorithms are performed when a
transmit has failed due to a maximum retry count (1 to 15, where max is
considered the wraparound case of 0).
