From 7e26bf45e4cb4ffaa113dc4a95a3d78bcc51e4cb Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Thu, 23 Mar 2017 12:27:12 +0200 Subject: [PATCH] net: bridge: allow SW learn to take over HW fdb entries Allow to take over an entry which was previously learned via HW when it shows up from a SW port. This is analogous to how HW takes over SW learned entries already. Suggested-by: Roopa Prabhu Signed-off-by: Nikolay Aleksandrov Reviewed-by: Ido Schimmel Signed-off-by: David S.
