[PATCH net-next 3/7] bonding: slight optimization for bond_alb_xmit()

From: Ding Tianhong
Date: Tue Dec 31 2013 - 04:47:55 EST


The bond_alb_xmit will check the return value for
bond_dev_queue_xmit() every time, but the bond_dev_queue_xmit()
is always return 0, it is no need to check the value every time,
so remove the unneed judgement for the xmit path.
