| /* Port Group IDs (PGID) are masks of destination ports. |
| * |
| * For L2 forwarding, the switch performs 3 lookups in the PGID table for each |
| * frame, and forwards the frame to the ports that are present in the logical |
| * AND of all 3 PGIDs. |
| * |
| * These PGID lookups are: |
| * - In one of PGID[0-63]: for the destination masks. There are 2 paths by |
| * which the switch selects a destination PGID: |
| * - The {DMAC, VID} is present in the MAC table. In that case, the |
| * destination PGID is given by the DEST_IDX field of the MAC table entry |
| * that matched. |
| * - The {DMAC, VID} is not present in the MAC table (it is unknown). The |
| * frame is disseminated as being either unicast, multicast or broadcast, |
| * and according to that, the destination PGID is chosen as being the |
| * value contained by ANA_FLOODING_FLD_UNICAST, |
| * ANA_FLOODING_FLD_MULTICAST or ANA_FLOODING_FLD_BROADCAST. |
| * The destination PGID can be an unicast set: the first PGIDs, 0 to |
| * ocelot->num_phys_ports - 1, or a multicast set: the PGIDs from |
| * ocelot->num_phys_ports to 63. By convention, a unicast PGID corresponds to |
| * a physical port and has a single bit set in the destination ports mask: |
| * that corresponding to the port number itself. In contrast, a multicast |
| * PGID will have potentially more than one single bit set in the destination |
| * ports mask. |
| * - In one of PGID[64-79]: for the aggregation mask. The switch classifier |
| * dissects each frame and generates a 4-bit Link Aggregation Code which is |
| * used for this second PGID table lookup. The goal of link aggregation is to |
| * hash multiple flows within the same LAG on to different destination ports. |
| * The first lookup will result in a PGID with all the LAG members present in |
| * the destination ports mask, and the second lookup, by Link Aggregation |
| * Code, will ensure that each flow gets forwarded only to a single port out |
| * of that mask (there are no duplicates). |
| * - In one of PGID[80-90]: for the source mask. The third time, the PGID table |
| * is indexed with the ingress port (plus 80). These PGIDs answer the |
| * question "is port i allowed to forward traffic to port j?" If yes, then |
| * BIT(j) of PGID 80+i will be found set. The third PGID lookup can be used |
| * to enforce the L2 forwarding matrix imposed by e.g. a Linux bridge. |
| */ |
| |
| /* Reserve some destination PGIDs at the end of the range: |
| * PGID_BLACKHOLE: used for not forwarding the frames |
| * PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses |
| * of the switch port net devices, towards the CPU port module. |
| * PGID_UC: the flooding destinations for unknown unicast traffic. |
| * PGID_MC: the flooding destinations for non-IP multicast traffic. |
| * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic. |
| * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic. |
| * PGID_BC: the flooding destinations for broadcast traffic. |
