Subject: [PATCH 3/4] net: dsa: qca8k: enable flooding to both CPU port
|
|
|
|
|
|
|
|
|
|
To permit a multi-CPU setup, flood all unknown frames to all CPU ports.
|
|
|
|
|
Each CPU port should have correct LOOKUP MEMBER configuration to
|
|
|
|
|
prevent receiving duplicate packets from user ports.
