Subject: forcedeth: new backoff implementation (update)
From: Ayaz Abdulla <aabdulla@xxxxxxxxxx>
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).
