From cd99c3776351e1b90ac05ff527553f8a29c03583 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Fri, 9 Jun 2017 17:58:08 +0200 Subject: [PATCH] bonding: warn user when 802.3ad speed is unknown Goal is to advertise the user when ethtool speeds and 802.3ad speeds are desynchronized. When this case happens, the kernel needs to be patched. Suggested-by: Andrew Lunn Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
