setting arp monitor in bonding (TUN/TAP driver not support Mii status)
link down!
I am not sure I understand your setup completely ...
But as stated in bonding.txt, the ARP monitor requires the underlying
driver to update dev->trans_start and dev->last_rx.
Since the TUN/TAP driver doesn't maintain these, it could very well
explain the behavior you are seeing.
The patch below adds the required functionality to the TUN/TAP driver.
Please test if this helps in your case.
