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 <nikolay@cumulusnetworks.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
