====================
s390/qeth: fixes 2018-06-29
please apply a few qeth fixes for -net and your 4.17 stable queue.
Patches 1-3 fix several issues wrt to MAC address management that were
introduced during the 4.17 cycle.
Patch 4 tackles a long-standing issue with busy multi-connection workloads
on devices in af_iucv mode.
Patch 5 makes sure to re-enable all active HW offloads, after a card was
previously set offline and thus lost its HW context.
