Removed changes to introduce asserts from "virtio-net: Return an error when vhost cannot enable RSS". Reorganized patches "virtio-net: Return an error when vhost cannot enable RSS" and "virtio-net: Do not clear VIRTIO_NET_F_RSS". This version now contains patches "virtio-net: Return an error when vhost cannot enable RSS" and "virtio-net: Enable software RSS". Rebased. V4 -> V5: Added patch "virtio-net: Do not write hashes to peer buffer". V3 -> V4: Extract patches "tap: Remove tap_receive()" and "net: Remove flag propagation" from "net: Remove receive_raw()". Added patch "virtio-net: Always set populate_hash". Added patch "virtio-net: Do not clear VIRTIO_NET_F_HASH_REPORT". Added patch "ebpf: Use standard section name". Added patch "ebpf: Simplify error handling". Added patch "ebpf: Return 0 when configuration fails". Added patch "ebpf: Refactor tun_rss_steering_prog()". Added patch "ebpf: Add a separate target for skeleton". V2 -> V3: Added patch "tap: Remove tap_probe_vnet_hdr_len()". Added patch "tap: Remove qemu_using_vnet_hdr()". Added patch "net: Move virtio-net header length assertion". Added patch "net: Remove receive_raw()". Added patch "tap: Shrink zeroed virtio-net header". Dropped patch "tap: Fix virtio-net header buffer size". V1 -> V2: Added patch "ebpf: Fix RSS error handling".
