Note: Driver modifies its struct net_device_ops. This will break if used for
multiple devices that are not all the same (if that HW config is possible).

Not much of a conversion anyway - macvlan has no way to change the offload
settings independently to its base device.

Like other virtual interfaces, e.g. br0, we don't need a transmit
queue. Packets should only be queued on real interfaces which are
underneath. In practice this patch makes little difference since the
virtual interfaces can accept packets as fast as they come, but the
patch will avoid bufferbloat questions to the mailling lists in the
future.
