The byte_unread is increased by the length of the skbuff when skbuff is
enqueued, and it is decreased when dequeued.

This patch adds two tests for ioctl SIOCINQ for SOCK_STREAM and
SOCK_SEQPACKET. The client waits for the server to send data, and checks if
the return value of the SIOCINQ is the size of the data. Then, consumes the
data and checks if the value is 0.

No comments since last month.
The patch [1], which adds SIOCINQ ioctl support for vsock, depends on this
patch. Could I get more eyes on this one?

This patch adds SIOCINQ ioctl tests for both SOCK_STREAM and
SOCK_SEQPACKET.
The client waits for the server to send data, and checks if the SIOCINQ
ioctl value matches the data size. After consuming the data, the client
checks if the SIOCINQ value is 0.

The value of the SIOCINQ is obtained by `virtio_transport_unread_bytes()`,
which is generic for all virtio transports. The function acquires the
`rx_lock` and returns the value of `rx_bytes`.

Add SIOCINQ ioctl tests for both SOCK_STREAM and SOCK_SEQPACKET.
The client waits for the server to send data, and checks if the SIOCINQ
ioctl value matches the data size. After consuming the data, the client
checks if the SIOCINQ value is 0.

Wrap the ioctl in `ioctl_int()`, which takes a pointer to the actual
int value and an expected int value. The function will not return until
either the ioctl returns the expected value or a timeout occurs, thus
avoiding immediate failure.
