Subject: [PATCH] net: bridge: switchdev: Include local flag in FDB
|
|
notifications
|
|
|
|
Some switchdev drivers, notably DSA, ignore all dynamically learned
|
|
address notifications (!added_by_user) as these are autonomously added
|
|
by the switch. Previously, such a notification was indistinguishable
|
|
from a local address notification. Include a local bit in the
|
|
notification so that the two classes can be discriminated.
|
|
|
|
This allows DSA-like devices to add local addresses to the hardware
|
|
FDB (with the CPU as the destination), thereby avoiding flows towards
|
|
the CPU being flooded by the switch as unknown unicast.
