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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
