  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.
