Subject: [34/71] PCH_GbE : Fixed the issue of collision detection

2.6.38-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Toshiharu Okada <toshiharu-linux@....okisemi.com>

commit ce3dad0f74e6b240f0b1dedbd8ea268a3f298d82 upstream.

The collision detection setting was invalid.
When collision occurred, because data was not resent,
there was an issue to which a transmitting throughput falls.

This patch enables the collision detection.
