From 70e4272b4c81828e7d942209bae83b9d92752cfe Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Sat, 24 Nov 2018 04:34:21 +0200 Subject: net: bridge: add no_linklocal_learn bool option Use the new boolopt API to add an option which disables learning from link-local packets. The default is kept as before and learning is enabled. This is a simple map from a boolopt bit to a bridge private flag that is tested before learning. v2: pass NULL for extack via sysfs Signed-off-by: Nikolay Aleksandrov Reviewed-by: Andrew Lunn Signed-off-by: David S.
