[RFC PATCH v2 net-next 13/17] net: dsa: mv88e6xxx: Request assisted learning on CPU port

From: Vladimir Oltean <olteanv@gmail.com>
Date: 2021-02-24 11:48:56
Subsystem: marvell 88e6xxx ethernet switch fabric driver, networking drivers, networking [dsa], the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Vladimir Oltean, Linus Torvalds

From: Tobias Waldekranz <tobias@waldekranz.com>

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.
