Subject: [PATCH net-next v2 0/3] This patch series introduce the support for ioctl(s) in AF_VSOCK.

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.

v1->v2
Applied all Stefano's suggestions:
    - vsock_do_ioctl has been rewritten
    - ioctl(SIOCOUTQ) test is skipped when it is not supported
    - Minor variable/function name changes
    - rebased to latest net-next

Luigi Leonardi (3):
  vsock: add support for SIOCOUTQ ioctl for all vsock socket types.
  vsock/virtio: add SIOCOUTQ support for all virtio based transports
  test/vsock: add ioctl unsent bytes test
