Subject: [PATCH 1/3] chelsio: remove unused code for 1G boards

From: Stephen Hemminger <[email-masked]>
Date: Tue, 20 Feb 2007 15:58:00 -0800

Some code for Chelsio 1G boards was put in the driver
based on the vendor version (minus TOE). Well some of those board
versions are only supported with TOE on the vendor driver, so additional
dead code was added.
