bonding: update documentation section after dev->trans_start removal
Drivers that use LLTX need to update trans_start of the netdev_queue. (Most drivers don't use LLTX; stack does this update if .ndo_start_xmit returned TX_OK). Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>

The ARP monitor relies on the device driver itself to verify
that traffic is flowing. In particular, the driver must keep up to
-date the last receive time, dev->last_rx, and transmit start time,
-dev->trans_start. If these are not updated by the driver, then the

+flag must also update netdev_queue->trans_start. If they do not, then the
ARP monitor will immediately fail any slaves using that driver, and
those slaves will stay down. If networking monitoring (tcpdump, etc)
shows the ARP requests and replies on the network, then it may be that
