====================
s390/qeth: updates 2020-08-27

please apply the following patch series for qeth to netdev's net-next tree.

Patch 8 makes some improvements to how we handle HW address events,
avoiding some uncertainty around processing stale events after we
switched off the feature.
Except for that it's all straight-forward cleanups.
