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. 64 */ 65 #define PGID_BLACKHOLE 57 66 #define PGID_CPU 58 67 #define
