From dd082716b43a3684b2f473ae5d1e76d1c076d86d Mon Sep 17 00:00:00 2001 From: Tobias Waldekranz Date: Sat, 16 Jan 2021 02:25:12 +0100 Subject: [PATCH] net: dsa: Include local addresses in assisted CPU port learning Add local addresses (i.e. the ports' MAC addresses) to the hardware FDB when assisted CPU port learning is enabled. NOTE: The bridge's own MAC address is also "local". If that address is not shared with any port, the bridge's MAC is not be added by this functionality - but the following commit takes care of that case.
