From 4d4ac1b0927c046413f0e92c38a833335a2d7590 Mon Sep 17 00:00:00 2001 From: dingtianhong Date: Thu, 2 Jan 2014 09:13:02 +0800 Subject: [PATCH] bonding: slight optimization for bond_alb_xmit() 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.
