[PATCH] AT91RM9200 Ethernet #2: MII interface
Adds support for the MII ioctls via generic_mii_ioctl(). Patch from Brian Stafford. Set the mii.phy_id to the detected PHY address, otherwise ethtool cannot access PHYs other than 0. Patch from Roman Kolesnikov. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
