Subject: [RFC net-next 0/7] net: dsa: Sync local bridge FDB addresses to hardware
Date: Sat, 16 Jan 2021 02:25:08 +0100	[thread overview]
Message-ID: <20210116012515.3152-1-tobias@waldekranz.com> (raw)

This is an extension of previous work done by Vladimir Oltean:
https://lore.kernel.org/netdev/20210106095136.224739-1-olteanv@gmail.com/

With this series, local addresses belonging to bridge ports or to the
bridge itself are also synced down to the hardware FDB. As a result
the hardware can avoid flooding return traffic to the CPU which is not
only inefficient but also very confusing to users:

https://lore.kernel.org/netdev/CAGwvh_MAQWuKuhu5VuYjibmyN-FRxCXXhrQBRm34GShZPSN6Aw@mail.gmail.com/
https://lore.kernel.org/netdev/6106e3d5-31fc-388e-d4ac-c84ac0746a72@prevas.dk/

Patch 1 through 3 extends the switchdev fdb notifications to include
the local flag, and to handle the case when an entry is added to the
bridge itself.

Patches 4 through 6 enables DSA to make use of those extensions.

Finally, enable assisted learning on the CPU port for mv88e6xxx.
