Merge branch 's390-net-next'

Julian Wiedmann says:

===================
s390/net: updates 2020-10-01

Patches 1-3 enable qeth to also support the .set_channels() ethtool
callback for OSA devices. This completes support for the full range
of device types.

The other patches are just the usual mix of cleanups.
(Even one for ctcm!)
