The RSS hashing type specifies the portion of received network data that a NIC must use to calculate an RSS hash value. Overlying drivers set the hash type, function, and indirection table. The hash type that the overlying driver sets can be a subset of the type that the miniport driver can support. WebbRSS Flow Steering.
