 *
 * @SOCK_DGRAM - datagram (conn.less) socket
 * @SOCK_STREAM - stream (connection) socket
 * @SOCK_RAW - raw socket
 * @SOCK_RDM - reliably-delivered message
 * @SOCK_SEQPACKET - sequential packet socket
 * @SOCK_PACKET - linux specific way of getting packets at the dev level.
 *            For writing rarp and other similar things on the user level.
