VIRTIO_NET_F_RSC_EXT feature bit indicates that the device is able to provide extended RSC information. When the feature is negotiatede and 'gso_type' field in received packet is not GSO_NONE, the device reports number of coalesced packets in 'csum_start' field and number of duplicated acks in 'csum_offset' field and sets VIRTIO_NET_HDR_F_RSC_INFO in 'flags' field.

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>
