Subject: [PATCH 2/3] net: dsa: qca8k: use correct CPU port when having multi
|
|
CPU ports
|
|
|
|
DSA framework call dsa_tree_setup_cpu_ports() to find a default CPU port.
|
|
If .preferred_default_local_cpu_port() isn't implemented, it will use the
|
|
first CPU port, which is different from qca8k_find_cpu_port().
