[TG3]: Reset chip when changing MAC address
Do the full chip reset when changing MAC address if ASF is enabled. ASF sometimes uses a different MAC address than the driver. Without the reset, the ASF MAC address may be overwritten when the driver's MAC address is changed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
