This is a note to let you know that I've just added the patch titled net: use netif_is_bridge_port() to check for IFF_BRIDGE_PORT to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-use-netif_is_bridge_port-to-check-for-iff_bridge.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c534f5ba184975c8a56c434ef2e92f8313362b52 Author: Julian Wiedmann <jwi@xxxxxxxxxxxxx> Date: Thu Feb 20 09:00:07 2020 +0100 net: use netif_is_bridge_port() to check for IFF_BRIDGE_PORT [ Upstream commit 2e92a2d0e450740ebe7e7a816162327ad1fde94b ] Trivial cleanup, so that all bridge port-specific code can be found in one go.
