[PATCH] skge: speed setting
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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
