There are 2 paths by * which the switch selects a destination PGID: * - The {DMAC, VID} is present in the MAC table. In that case, the * destination PGID is given by the DEST_IDX field of the MAC table entry * that matched. * - The {DMAC, VID} is not present in the MAC table (it is unknown). The * frame is disseminated as being either unicast, multicast or broadcast, * and according to that, the destination PGID is chosen as being the * value contained by ANA_FLOODING_FLD_UNICAST, * ANA_FLOODING_FLD_MULTICAST or ANA_FLOODING_FLD_BROADCAST. * The destination PGID can be an unicast set: the first PGIDs, 0 to * ocelot->num_phys_ports - 1, or a multicast set: the PGIDs from * ocelot->num_phys_ports to 63. By convention, a unicast PGID corresponds to * a physical port and has a single bit set in the destination ports mask: * that corresponding to the port number itself. In contrast, a multicast * PGID will have potentially more than one single bit set in the destination * ports mask. * - In one of PGID[64-79]: for the aggregation mask. The switch classifier * dissects each frame and generates a 4-bit Link Aggregation Code which is * used for this second PGID table lookup. The goal of link aggregation is to * hash multiple flows within the same LAG on to different destination ports. * The first lookup will result in a PGID with all the LAG members present in * the destination ports mask, and the second lookup, by Link Aggregation * Code, will ensure that each flow gets forwarded only to a single port out * of that mask (there are no duplicates). * - In one of PGID[80-90]: for the source mask. The third time, the PGID table * is indexed with the ingress port (plus 80). These PGIDs answer the * question "is port i allowed to forward traffic to port j?" If yes, then * BIT(j) of PGID 80+i will be found set. The third PGID lookup can be used * to enforce the L2 forwarding matrix imposed by e.g. a Linux bridge. */ /* Reserve some destination PGIDs at the end of the range: * PGID_BLACKHOLE: used for not forwarding the frames * PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses * of the switch port net devices, towards the CPU port module. * PGID_UC: the flooding destinations for unknown unicast traffic. * PGID_MC: the flooding destinations for non-IP multicast traffic. * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic. * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic. * PGID_BC: the flooding destinations for broadcast traffic. */ #define PGID_BLACKHOLE 57 #define PGID_CPU 58 #define PGID_UC 59 #define PGID_MC 60 #define
