Subject: [PATCH 2/4] net: dsa: qca8k: limit user ports access to the first CPU
|
||
|
|
port on setup
|
||
|
|
|
||
|
|
In preparation for multi-CPU support, set CPU port LOOKUP MEMBER outside
|
||
|
|
the port loop and setup the LOOKUP MEMBER mask for user ports only to
|
||
|
|
the first CPU port.
|
||
|
|
|
||
|
|
This is to handle flooding condition where every CPU port is set as
|
||
|
|
target and prevent packet duplication for unknown frames from user ports.
|
||
|
|
|
||
|
|
Secondary CPU port LOOKUP MEMBER mask will be setup later when
|
||
|
|
port_change_master will be implemented.
