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.

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> ---

From: Jiri Pirko <jiri at nvidia.com> Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when set implicates that the driver provides the exact size of the header. Quoting the original virtio spec: "hdr_len is a hint to the device as to how much of the header needs to be kept to copy into each packet" "a hint" might not be clear for the reader what does

From: Jiri Pirko <jiri at nvidia.com> virtio_net_hdr_from_skb() fills up hdr_len to skb_headlen(skb). Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when set implicates that the driver provides the exact size of the header. The driver already complies to fill the correct value. Introduce the feature and advertise it. Signed-off-by: Jiri Pirko <jiri at nvidia.com>
