Subject: [PATCH] drivers: net: mscc_ocelot: don't flood unicast traffic to cpu
|
||
|
|
|
||
|
|
Switch cpu port doesn't learn MAC addresses and the local bridge dev_addr
|
||
|
|
must be explicitly added to the bridge.
|
||
|
|
This is done whenever a port is added to a bridge, ports following the
|
||
|
|
1st one will just overwrite the same entry.
|
||
