A ternary match table is used for RFS. If multiple entries in the table match, the entry with the lowest numerical values index is chosen as the matching entry. Entries in the table are identified using an index which takes a value from 0 to PRFSCAPR[NUM_RFS]-1 when accessed by the PSI (PF). Portions of the RFS table can be assigned to each SI by the PSI (PF) driver in PSIaRFSCFGR. Assignments are cumulative, the entries assigned to SIn start after those assigned to SIn-1. The total assignments to all SIs must be equal to or less than the number available to the port as found in PRFSCAPR. For RSS, the Toeplitz hash function used requires two inputs, a 40B random secret key that is supplied through the PRSSKR0-9 registers as well as the relevant pieces of the packet header (n-tuple). The 6 LSB bits of the hash function result will then be used as a pointer to obtain the tag referenced in the 64 entry indirection table. The result will provide a winning group which will be used to help route the received packet.
