Subject: [PATCH] net: dsa: qca8k: enable assisted learning on CPU port
|
|
|
|
Enable assisted learning on CPU port.
|
|
|
|
It has been verified that there is a problem in packet roaming
|
|
from one BSS to another in the same security settings from one
|
|
physical R7800 to another physical R7800 where they are in the
|
|
same L2 broadcast domain backhauled/linked together via one
|
|
of the ethernet ports.
|
|
DHCP will fail to complete and traffic cannot flow for around 300
|
|
seconds.
|
