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

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

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