[patch net-next 3/3] mlxsw: spectrum: Use per-netns netdevice notifier registration

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

The mlxsw_sp instance is not interested in events happening in other
network namespaces. So use "_net" variants for netdevice notifier
registration/unregistration and get only events which are happening in
the net the instance is in.
