22:21:37 2023 +0000 virtio/vsock: replace virtio_vsock_pkt with sk_buff This commit changes virtio/vsock to use sk_buff instead of virtio_vsock_pkt. Beyond better conforming to other net code, using sk_buff allows vsock to use sk_buff-dependent features in the future (such as sockmap) and improves throughput.
