It was outlined in the cover letter for the RFC [1]. But, briefly: we set a number of queues (say 16) via ethtool. We then create a series of n-tuple filters directing certain flows to queues 0-7 via a custom RSS context. The remaining queues, 8-15 are for all other flows via the default RSS context. Queues 0-7 are used with busy polling from userland so we want those queues to have a larger rx/tx-usecs rx/tx-frames than queues 8-15. We implemented basic support for this in the RFC we sent to the mailing list. [1]: https://lore.kernel.org/lkml/20230823223121.58676-1-dev@xxxxxxxxxxxx/
