From 29112f4e248ca6941f2233f6ed96a7283a67cced Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Fri, 24 Apr 2009 01:58:23 +0000 Subject: [PATCH] bonding: use ethtool for link checking first This patch only changes the order of interfaces to use for checking slave link status in bond_check_dev_link() to priorize ethtool interface. Should safe some troubles as ethtool seems to be more supported.
