[PATCH] sky2: phy power problems on 88e805X chips
On the 88E805X chipsets (used in laptops), the PHY was not getting powered out of shutdown properly. The variable reg1 was getting reused incorrectly. This is probably the cause of the bug. http://bugzilla.kernel.org/show_bug.cgi?id=6471 Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
