6. Queue by RSS (if RSS enabled) - Identifies one of 1 x 4 queues through the RSS index. The

following modes are supported:

—No RSS — The default queue as defined in MRQC.DEF_Q is used for packets that do not meet

any of the previous conditions.

—RSS only — A set of 4 queues is allocated for RSS. The queue is identified through the RSS

index. Note that it is possible to use a subset of the 4 queues.

Note: No RSS here mean either that RSS is disabled (MRQC.Multiple Receive Queues Enable field

equals 000b) or that the packet did not match any of the RSS filters.

Figure 7-7 shows the receive queue assignment flow.
