====================
s390/qeth: updates 2019-12-23

please apply the following patch series for qeth to your net-next tree.

This reworks the RX code to use napi_gro_frags() when building non-linear
skbs, along with some consolidation and cleanups.

Happy holidays - and many thanks for all the effort & support over the past
year, to both Jakub and you. It's much appreciated.
