/* Port Group IDs (PGID) are masks of destination ports.
|
|
*
|
|
* For L2 forwarding, the switch performs 3 lookups in the PGID table for each
|
|
* frame, and forwards the frame to the ports that are present in the logical
|
|
* AND of all 3 PGIDs.
|
|
*
|
|
* These PGID lookups are:
|
|
* - In one of PGID[0-63]: for the destination masks. 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_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.
