Arnd Bergmann 8a83a00b07 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.
