net: RPS: Enable hardware acceleration of RFS
Allow drivers for multiqueue hardware with flow filter tables to
accelerate RFS. The driver must:
1. Set net_device::rx_cpu_rmap to a cpu_rmap of the RX completion
IRQs (in queue order). This will provide a mapping from CPUs to the
queues for which completions are handled nearest to them.
2. Implement net_device_ops::ndo_rx_flow_steer. This operation adds
or replaces a filter steering the given flow to the given RX queue, if
possible.
3. Periodically remove filters for which rps_may_expire_flow() returns
true.
