[PATCH] emac: add support for platform-specific unsupported PHY features
This patch adds support to the ibm_emac driver for platform-specific unsupported PHY features. The patch attempts to determine the highest speed and duplex when autonegotiation is unsupported. Signed-off-by: Wade Farnsworth <wfarnsworth@mvista.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
