Subject: s390/qeth: support net namespaces for L3 devices
Git-commit: b8f14878e6ae210cad4025bfc97dca877b4df721
Patch-mainline: v5.7-rc1
References: git-fixes

Enable the L3 driver's IPv4 address notifier to watch for events on qeth
devices that have been moved into a net namespace. We need to program
those IPs into the HW just as usual, otherwise inbound traffic won't
flow.

Fixes: 6133fb1aa137 ("[NETNS]: Disable inetaddr notifiers in namespaces other than initial.")
