14/* Port Group IDs (PGID) are masks of destination ports.
15 *
16 * For L2 forwarding, the switch performs 3 lookups in the PGID table for each
17 * frame, and forwards the frame to the ports that are present in the logical
18 * AND of all 3 PGIDs.
19 *
20 * These PGID lookups are:
21 * - In one of PGID[0-63]: for the destination masks. There are 2 paths by
22 *   which the switch selects a destination PGID:
23 *     - The {DMAC, VID} is present in the MAC table. In that case, the
24 *       destination PGID is given by the DEST_IDX field of the MAC table entry
25 *       that matched.
26 *     - The {DMAC, VID} is not present in the MAC table (it is unknown). The
27 *       frame is disseminated as being either unicast, multicast or broadcast,
28 *       and according to that, the destination PGID is chosen as being the
29 *       value contained by ANA_FLOODING_FLD_UNICAST,
30 *       ANA_FLOODING_FLD_MULTICAST or ANA_FLOODING_FLD_BROADCAST.
31 *   The destination PGID can be an unicast set: the first PGIDs, 0 to
32 *   ocelot->num_phys_ports - 1, or a multicast set: the PGIDs from
33 *   ocelot->num_phys_ports to 63. By convention, a unicast PGID corresponds to
34 *   a physical port and has a single bit set in the destination ports mask:
35 *   that corresponding to the port number itself. In contrast, a multicast
36 *   PGID will have potentially more than one single bit set in the destination
37 *   ports mask.
38 * - In one of PGID[64-79]: for the aggregation mask. The switch classifier
39 *   dissects each frame and generates a 4-bit Link Aggregation Code which is
40 *   used for this second PGID table lookup. The goal of link aggregation is to
41 *   hash multiple flows within the same LAG on to different destination ports.
42 *   The first lookup will result in a PGID with all the LAG members present in
43 *   the destination ports mask, and the second lookup, by Link Aggregation
44 *   Code, will ensure that each flow gets forwarded only to a single port out
45 *   of that mask (there are no duplicates).
46 * - In one of PGID[80-90]: for the source mask. The third time, the PGID table
47 *   is indexed with the ingress port (plus 80). These PGIDs answer the
48 *   question "is port i allowed to forward traffic to port j?" If yes, then
49 *   BIT(j) of PGID 80+i will be found set. The third PGID lookup can be used
50 *   to enforce the L2 forwarding matrix imposed by e.g. a Linux bridge.
51 */
52
53/* Reserve some destination PGIDs at the end of the range:
54 * PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses
55 *           of the switch port net devices, towards the CPU port module.
56 * PGID_UC: the flooding destinations for unknown unicast traffic.
57 * PGID_MC: the flooding destinations for broadcast and non-IP multicast
58 *          traffic.
59 * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic.
60 * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic.
