Bug description:
* Explain the bug(s)
There is possible deadlock during reload mlxsw into initial netns made
possible by commit:
328fbe747ad4 ("net: Close race between {un, }register_netdevice_notifier()
and setup_net()/cleanup_net()").
* Brief explanation of fixes
Introduce dev_net variant that is basically per-net notifier with an
extension that re-registers the per-net notifier upon netdev namespace
change. Basically the per-net notifier follows the netdev into
namespace.
* How to test
# chroot /host nsenter -t 1 -n devlink dev reload ${port} netns ${NS}
* What it could break
none
