From 4f89f5b5353cae2e056713e823819f24cad92bc3 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Fri, 7 Dec 2018 19:55:04 +0000 Subject: vxlan: Add vxlan_fdb_replay() When a VXLAN device becomes relevant to a driver (such as when it is attached to an offloaded bridge), the driver will generally need to walk the existing FDB entries and offload them. Add a function vxlan_fdb_replay() to call a given notifier block for each FDB entry with a given VNI. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S.
