This allows to offload bridges with DSA to the switch hardware and do the packet forwarding in hardware. This implements generic functions to access the switch hardware tables, which are used to control many features of the switch. This patch activates the MAC learning by removing the MAC address table lock, to prevent uncontrolled forwarding of packets between all the LAN ports, they are added into individual bridge tables entries with individual flow ids and the switch will do the MAC learning for each port separately before they are added to a real bridge. Each bridge consist of an entry in the active VLAN table and the VLAN mapping table, table entries with the same index are matching. In the VLAN unaware mode we configure everything with VLAN ID 0, but we use different flow IDs, the switch should handle all VLANs as normal payload and ignore them. When the hardware looks for the port of the destination MAC address it only takes the entries which have the same flow ID of the ingress packet. The bridges are configured with 64 possible entries with these information: Table Index, 0...63 VLAN ID, 0...4095: VLAN ID 0 is untagged flow ID, 0..63: Same flow IDs share entries in MAC learning table port map, one bit for each port number tagged port map, one bit for each port number Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
