different rx queues based on a hash value. We only create one, because 2390 * we want to scatter any traffic we can apply RSS to across all our rx 2391 * queues. Anything else will only be delivered to the first rx queue, 2392 * which doesn't require an RQT. 2393 * 2394 * A Transport Interface Receive (TIR) delivers packets to either a single rx 2395 * queue or an RQT, and in the latter case, specifies the set of fields 2396 * hashed, the hash function, and the hash key. We need one of these for each 2397 * type of RSS traffic - v4 TCP, v6 TCP, v4 UDP, v6 UDP, other v4, other v6, 2398 * and one for non-RSS traffic. 2399 * 2400 * Flow tables hold flow table entries in sequence. The first entry that 2401 * matches a packet is applied, sending the packet to either another flow 2402 * table or a TIR. We use one flow table to select packets based on 2403 * destination MAC address, and a second to apply RSS. The entries in the 2404 * first table send matching packets to the second, and the entries in the 2405 * RSS table send packets to RSS TIRs if possible, or the non-RSS TIR. 2406 * 2407 * The flow table entry that delivers packets to an RSS TIR must include match 2408 * criteria that ensure packets delivered to the TIR include all the fields 2409 * that the TIR hashes on - so for a v4 TCP TIR, the flow table entry must 2410 * only accept v4 TCP packets. Accordingly, we need flow table entries for 2411 * each TIR. 2412 * 2413 * All of this is a lot more flexible than we need, and we can describe most 2414 * of the stuff we need with a simple array. 2415 * 2416 * An RSS config creates a TIR with hashing enabled on a set of fields, 2417 * pointing to either the first rx queue or the RQT containing all the rx 2418 * queues, and a flow table entry that matches on an ether type and 2419 * optionally an ip proto, that delivers packets to the TIR. 2420 */ 2421 static struct mcx_rss_rule { 2422 int hash_sel;
