Subject: mlx5e throwing RTNL_ASSERT error on vxlan_get_rx_port

>From what I can tell it looks like the recent commit that changed the
behavior for vxlan_get_rx_port has broken the mlx5 driver as it was
calling vxlan_get_rx_port in mlx5e_create_netdev which didn't hold the
rtnl lock.  As a result it is throwing RTNL_ASSERT errors.

I'm not sure if anyone has already seen this or not but I thought I
would bring it to your attention.  Odds are this probably something
that needs to be fixed in the mlx5e driver and if I have time I might
get to it sometime in the next several days if nobody else ends up
addressing it.

Thanks.
