From: Tobias Waldekranz Subject: [RFC net-next 7/7] net: dsa: mv88e6xxx: Request assisted learning on CPU port Date: Sat, 16 Jan 2021 02:25:15 +0100 Archived-At: While the hardware is capable of performing learning on the CPU port, it requires alot of additions to the bridge's forwarding path in order to handle multi-destination traffic correctly. Until that is in place, opt for the next best thing and let DSA sync the relevant addresses down to the hardware FDB.
