Merge branch 's390-qeth-fixes' 

Julian Wiedmann says:

====================
s390/qeth: fixes 2018-11-02

please apply one round of qeth fixes for -net.

Patch 1 is rather large and removes a use-after-free hazard from many of our
debug trace entries.
Patch 2 is yet another fix-up for the L3 subdriver's new IP address management
code.
Patch 3 and 4 resolve some fallout from the recent changes wrt how/when qeth
allocates its net_device.
Patch 5 makes sure we don't set reserved bits when building HW commands from
user-provided data.
And finally, patch 6 allows ethtool to play nice with new HW.
