Subject: net_sched: use macvlan real dev trans_start in dev_trans_start()
Patch-mainline: v4.15-rc3
Git-commit: 32d3e51a82d453762ef148b2c4fbc8a7ec374a88
References: bsc#1109837

Macvlan devices are similar to vlans and do not update their
own trans_start. In order for arp monitoring to work for a bond device
when the slaves are macvlans, obtain its real device.
