From eb100e0e24a23f309d0765061ea4dfd8ca9d400d Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Thu, 23 Mar 2017 12:27:13 +0200 Subject: [PATCH] net: bridge: allow to add externally learned entries from user-space The NTF_EXT_LEARNED flag was added for switchdev and externally learned entries, but it can also be used for entries learned via a software in user-space which requires dynamic entries that do not expire. One such case that we have is with quagga and evpn which need dynamic entries but also require to age them themselves.
