During refactoring of ksz spi probe, ds->configure_vlan_while_filtering flag is set in the ksz_setup function. It makes the extack warning when vlan_add command is used when vlan_filtering is turned off for the port. To allow the vlan_add for the bridge vlan unaware ports, private pvid is used for it. This pvid is used for the vlan_unaware ports. The private pvid is added to the vlan_table during the port_setup function. For the vlan aware ports, pvid issued by the user application will be used. Bridge vlan pvid is stored in the ksz port structure which can be used during transition between the vlan aware to unaware and vice versa.
Tested using the following sequence for ksz9477 and lan937x ---------------- Setup -> Host1 --- LAN1 -- LAN2 --- Host2
ip link set dev br0 type bridge vlan_filtering 0 bridge vlan add vid 5 dev lan1 pvid untagged bridge vlan add vid 5 dev lan2 pvid untagged bridge vlan del vid 5 dev lan1 bridge vlan del vid 5 dev lan2
After each step of execution, transmitted the packets from Host1 and successfully received by the Host2.
