Public API is four functions:* fman_kg_init(sc) -- Initialize KeyGen subsystem, clear out any stale config.* fman_kg_fini(sc) -- Teardown KeyGen* fman_kg_alloc_hash_scheme(sc, port, base_fqid, nfqs) -- Allocate a scheme, program it for RSS-over-IP-5-tuple hashing to nfqs FQs starting at base_fqid, bind it to port.* fman_kg_free_hash_scheme(sc, port) -- Remove a scheme added by fman_kg_alloc_hash_scheme().KeyGen state (bitmap + port->scheme table) is added to the fman softc.Future work may allow configuring the KG hash inputs, but what we havenow (5-tuple of src/src-port/dst/dst-port/IPSec SPI field) issufficient.
