Date: Wed, 7 Nov 2012 11:23:00 +0800 From: Zheng Li <zheng.x.li@...cle.com> To: netdev@...r.kernel.org, fubar@...ibm.com, andy@...yhouse.net Cc: linux-kernel@...r.kernel.org, davem@...emloft.net, joe.jin@...cle.com, zheng.x.li@...cle.com Subject: [PATCH] bonding: rlb mode of bond should not alter ARP replies originating via bridge ARP traffic passing through a bridge and out via the bond (when the bond is a port of the bridge) should not have its source MAC address adjusted by the receive load balance code in rlb_arp_xmit.
