27 Contemporary NICs support multiple receive and transmit descriptor queues
461 XPS: Transmit Packet Steering
464 Transmit Packet Steering is a mechanism for intelligently selecting
465 which transmit queue to use when transmitting a packet on a multi-queue

484 This mapping is used to pick transmit queue based on the receive
486 queues can be mapped to a set of transmit queues (many:many), although
488 on the same queue associations for transmit and receive. This is useful for
494 transmit queue corresponding to the associated receive queue has benefits
495 in keeping the CPU overhead low. Transmit completion work is locked into

502 XPS is configured per transmit queue by setting a bitmap of
503 CPUs/receive-queues that may use that queue to transmit. The reverse
