Subject: [patch net-next 3/3] mlxsw: spectrum: Use per-netns netdevice notifier registration
Date: Mon, 30 Sep 2019 10:15:11 +0200	[thread overview]
Message-ID: <20190930081511.26915-4-jiri@resnulli.us> (raw)
In-Reply-To: <20190930081511.26915-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@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.
