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_BLACKHOLE: used for not forwarding the frames
55  * PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses
56  *           of the switch port net devices, towards the CPU port module.
57  * PGID_UC: the flooding destinations for unknown unicast traffic.
58  * PGID_MC: the flooding destinations for non-IP multicast traffic.
59  * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic.
60  * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic.
61  * PGID_BC: the flooding destinations for broadcast traffic.
