From 7bdb04ed0dbf9f0e94110be43db4f8bb7df58de2 Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Wed, 22 Jan 2014 14:53:23 +0100 Subject: [PATCH] bonding: convert arp_interval to use the new option API This patch adds the necessary changes so arp_interval would use the new bonding option API. The "default" definition has been removed as it was 0. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S.
