From 24e9fcb4cf4653bc4142fd05f3a87dc42f31375a Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Tue, 12 Nov 2013 15:37:40 +0100 Subject: [PATCH] bonding: don't permit to use ARP monitoring in 802.3ad mode [ Upstream commit ec9f1d15db8185f63a2c3143dc1e90ba18541b08 ] Currently the ARP monitoring is not supported with 802.3ad, and it's prohibited to use it via the module params. However we still can set it afterwards via sysfs, cause we only check for *LB modes there. To fix this - add a check for 802.3ad mode in bonding_store_arp_interval.
