If a host VMM administrator hoses his VF by assigning a port VLAN after
it is already up and running with implicit permission to set local
VLANs then we print a message warning the host administrator that the
VF driver needs to be reloaded.

In addition we need to knock the VF offline so that it does not continue
to receive traffic not on the port VLAN assigned to it.  So we reset the
VF.  The VF will cease operation and the administrator will be forced to
unload and reload the VF driver to make it work again.

Currently broadcasts are handled in network RX context, where
the packets are sent through netif_rx.  This means that the number
of macvlans will be constrained by the capacity of netif_rx.

For example, setting up 4096 macvlans practically causes all
broadcast packets to be dropped as the default netif_rx queue
size simply can't handle 4096 skbs being stuffed into it all
at once.

Fundamentally, we need to ensure that the amount of work handled
in each netif_rx backlog run is constrained.  As broadcasts are
anything but constrained, it either needs to be limited per run
or moved to process context.

This patch picks the second option and moves all broadcast handling
bar the trivial case of packets going to a single interface into
a work queue.  Obviously there also needs to be a limit on how
many broadcast packets we postpone in this way.  I've arbitrarily
chosen tx_queue_len of the master device as the limit (act_mirred
also happens to use this parameter in a similar way).

In order to ensure we don't exceed the backlog queue we will use
netif_rx_ni instead of netif_rx for broadcast packets.

This patch adds the helper __dev_forward_skb which is identical to

how the packet is injected, e.g., via netif_rx_ni or netif_receive_skb.
