net: maintain namespace isolation between vlan and real device
In the vlan and macvlan drivers, the start_xmit function forwards data to the dev_queue_xmit function for another device, which may potentially belong to a different namespace. To make sure that classification stays within a single namespace, this resets the potentially critical fields. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
