net-next merge Note:
When merged with net-next the following simple conflict will appear,

drivers/net/ethernet/mellanox/mlx5/core/en/port_buffer.c

++<<<<<<< HEAD (net)
 + *   max_mtu: netdev's max_mtu
++=======
+  *    @mtu: device's MTU
++>>>>>>> net-next

To resolve: just replace the line in net-next
*    @mtu: device's MTU
to
*    @max_mtu: netdev's max_mtu
