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