It is hard to say why the driver looks at dev_trans_start() of the slave->dev, considering that this is updated even by non-ARP/NS probes sent by us, and even by traffic not sent by us at all (for example PTP on physical slave devices). ARP monitoring in active-backup mode appears to still work even if we track only the last TX time of actual ARP probes.
