From c7d4e6ab3165693342c21f6faf80d983137fee0c Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Tue, 1 Nov 2022 15:27:43 +0100 Subject: net/mlx5e: Propagate an internal event in case uplink netdev changes Whenever uplink netdev is set/cleared, propagate newly introduced event to inform notifier blocks netdev was added/removed. Move the set() helper to core.c from header, introduce clear() and netdev_added_event_replay() helpers. The last one is going to be called from rdma driver, so export it.
