From: Jiri Pirko <jiri@mellanox.com> Some drivers, like mlxsw, are not interested in notifications coming in for netdevices from other network namespaces. So introduce per-netns notifiers and allow to reduce overhead by listening only for notifications from the same netns. This is also a preparation for upcoming patchset "devlink: allow devlink instances to change network namespace". This resolves deadlock during reload mlxsw into initial netns made possible by 328fbe747ad4 ("net: Close race between {un, }register_netdevice_notifier() and setup_net()/cleanup_net()").
