At Jason's request, I am trying to help finalize the spec for the new multiqueue feature. Changes from Jason's rfc: - reserved vq 3: this makes all rx vqs even and tx vqs odd, which looks nicer to me. - documented packet steering, added a generalized steering programming command. Current modes are single queue and host driven multiqueue, but I envision support for guest driven

RSS (Receive-side scaling) defines hash calculation rules and decision on receive virtqueue according to the calculated hash, provided mask to apply and provided indirection table containing indices of receive virqueues. The driver sends the control command to enable multiqueue and provide parameters for receive steering. Signed-off-by: Yuri Benditovich <yuri.benditovich at daynix.com> ---

All the classes of commands are defined without indentation. All the commands are defined with indentation of 1 space. Only the last one (VIRTIO_NET_CTRL_GUEST_OFFLOADS_SET at the end of the file) does not have an indentation. On Mon, Mar 2, 2020 at 12:54 PM Michael S.
