27 Contemporary NICs support multiple receive and transmit descriptor queues
29 queues to distribute processing among CPUs. The NIC distributes packets by
47 Some advanced NICs allow steering packets to queues based on
57 module parameter for specifying the number of hardware queues to
60 for each CPU if the device supports enough queues, or otherwise at least
66 default mapping is to distribute the queues evenly in the table, but the
69 indirection table could be done to give different queues different
80 of queues to IRQs can be determined from /proc/interrupts. By default,

420 queues can be mapped to a set of transmit queues (many:many), although
437 CPUs/receive-queues that may use that queue to transmit. The reverse
438 mapping, from CPUs to transmit queues or from receive-queues to transmit
439 queues, is computed and maintained for each network device. When
446 queues match, one is selected by using the flow hash to compute an index
