Merge branch 'netdev-ndo_tx_timeout-cleanup'

Michael S. Tsirkin says:

====================
netdev: ndo_tx_timeout cleanup

Yet another forward declaration I missed. Hopfully the last one ...

A bunch of drivers want to know which tx queue triggered a timeout,
and virtio wants to do the same.
We actually have the info to hand, let's just pass it on to drivers.
Note: tested with an experimental virtio patch by Julio.
That patch itself isn't ready yet though, so not included.
Other drivers compiled only.
