Merge branch 'netif_rx-part3'

Sebastian Andrzej Siewior says:

====================
net: Convert user to netif_rx(), part 3.

This is the third and last batch of converting netif_rx_ni() caller to
netif_rx(). The change making this possible is net-next and
netif_rx_ni() is a wrapper around netif_rx(). This is a clean up in
order to remove netif_rx_ni().

The micrel phy driver is patched twice within this series: the first is
is to replace netif_rx_ni() and second to move netif_rx() outside of the
IRQ-off section. It is probably simpler to keep it within this series.
