From: Cong Wang <[email protected]> Currently only unix stream socket sets TCP_ESTABLISHED, datagram socket can set this too when they connect to its peer socket. At least __ip4_datagram_connect() does the same.
This will be used by the next patch to determine whether an AF_UNIX datagram socket can be redirected in sockmap.
