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_CPU: used for whitelisting certain MAC addresses, such as the addresses 55 * of the switch port net devices, towards the CPU port module. 56 * PGID_UC: the flooding destinations for unknown unicast traffic. 57 * PGID_MC: the flooding destinations for broadcast and non-IP multicast 58 * traffic. 59 * PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic. 60 * PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic. 61 */ 62 #define PGID_CPU 59 63 #define PGID_UC 60 64 #define PGID_MC 61 65 #define PGID_MCIPV4 62 66 #define PGID_MCIPV6 63 67 68 #define
