Sockets support both read(2)/write(2) and send(2)/recv(2) system
calls. Each of these is actually a family of multiple system
calls such as send(2), sendfile(2), sendmsg(2), sendmmsg(2), and
sendto(2).
This patch claries which families of system calls can be used.

The AF_VSOCK address family has been available since Linux 3.9.
This patch adds vsock.7 and describes its use along the same lines as
existing ip.7, unix.7, and netlink.7 man pages.
