bonding, net: Move last_rx update into bonding recv logic
The only user of the net_device->last_rx field is bonding. This patch adds a conditional update of last_rx to the bonding special logic in skb_bond_should_drop, causing last_rx to only be updated when the ARP monitor is running. This frees network device drivers from the necessity of updating last_rx, which can have cache line thrash issues. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.
