Subject: [PATCH] net: dsa: Sync static FDB entries on foreign interfaces to
|
|
hardware
|
|
|
|
Reuse the "assisted_learning_on_cpu_port" functionality to always add
|
|
entries for user-configured entries on foreign interfaces, even if
|
|
assisted_learning_on_cpu_port is not enabled. E.g. in this situation:
|
|
|
|
br0
|
|
/ \
|
|
swp0 dummy0
|
|
|
|
$ bridge fdb add 02:00:de:ad:00:01 dev dummy0 vlan 1 master
|
|
|
|
Results in DSA adding an entry in the hardware FDB, pointing this
|
|
address towards the CPU port.
|
|
|
|
The same is true for entries added to the bridge itself, e.g:
|
|
|
|
$ bridge fdb add 02:00:de:ad:00:01 dev br0 vlan 1 self
