This patch series introduce the support for ioctl(s) in AF_VSOCK. The only ioctl currently available is SIOCOUTQ, which returns the number of unsent or unacked packets. It is available for SOCK_STREAM, SOCK_SEQPACKET and SOCK_DGRAM. As this information is transport-dependent, a new optional callback is introduced: stream_bytes_unsent. The first patch add ioctl support in AF_VSOCK, while the second patch introduce support for SOCK_STREAM and SOCK_SEQPACKET in all virtio-based transports: virtio_transport (G2H), vhost-vsock (H2G) and vsock-loopback. The latest patch introduce two tests for this new feature. More details can be found in each patch changelog.
