The reference manual -is somehow misleading when describing PORT_VLAN modes. It states that -PORT_MEM (VLAN port member) is used for destination if the VLAN table -lookup hits, but actually **PORT_MEM & PORT_MATRIX** (bitwise AND of -VLAN port member and port matrix) is used instead, which means we can -have two or more separate VLAN-aware bridges with the same PVID and -traffic won't leak between them. - -Therefore, to solve this, enable independent VLAN learning with PVID 0 -on VLAN-unaware bridges, by setting their PCR.PORT_VLAN to fallback -mode, while leaving standalone ports in port matrix mode. The CPU port -is always set to fallback mode to serve those bridges. - -During testing, it is found that FDB lookup with filter ID of 0 will -also hit entries with VID 0 even with independent VLAN learning. To -avoid that, install all VLANs with filter ID of 1. - -Signed-off-by: DENG Qingfang -Reviewed-by: Vladimir Oltean -Signed-off-by: David S.
