From fbf8b356e54080cd14da8163873d582982672589 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 20 Feb 2020 09:07:56 +0200 Subject: [PATCH] mlxsw: spectrum_router: Prepare function for router lock introduction The function removes the FDB entry that directs the macvlan's MAC to the router port. It is called from both the netdev notifier block and the inetaddr notifier block that will soon hold the router lock. Make sure that only the netdev notifier calls the exported version, so that is will take the router lock, which will already be held by the inetaddr notifier.
