This enables more ethtool information. The speed and settings of the underlying device are propagated up. This makes services like SNMP that use ethtool to get speed setting, work when managing a vlan, without adding silly heurtistics into SNMP daemon. For the driver info, just use existing driver strings. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
