[patch 06/10] tun/tap ARP monitor support

From: Tommy Christensen <redacted>

But as stated in bonding.txt, the ARP monitor requires the underlying
driver to update dev->trans_start and dev->last_rx.

The patch below adds the required functionality to the TUN/TAP driver.
Please test if this helps in your case.
