Subject: [PATCH] net: dsa: b53: Create default VLAN entry explicitly
|
|
|
|
In case CONFIG_VLAN_8021Q is not set, there will be no call down to the
|
|
b53 driver to ensure that the default PVID VLAN entry will be configured
|
|
with the appropriate untagged attribute towards the CPU port. We were
|
|
implicitly relying on dsa_slave_vlan_rx_add_vid() to do that for us,
|
|
instead make it explicit.
