Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Minor conflict in drivers/s390/net/qeth_l2_main.c, kept the lock
from commit c8183f548902 ("s390/qeth: fix potential deadlock on
workqueue flush"), removed the code which was removed by commit
9897d583b015 ("s390/qeth: consolidate some duplicated HW cmd code").
