[patch 29/39] [PATCH] skge: speed setting

From: Chris Wright
Date: Mon Feb 27 2006 - 17:45:26 EST


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

This is a clone of John Linville's fixed for speed setting on sky2 driver.
The skge driver has the same code (and bug). It would not allow manually forcing
100 and 10 mbit.
