78 * override the enum sock_type in include/linux/net.h, so
79 * we define ARCH_HAS_SOCKET_TYPES here.
80 *
81 * @SOCK_DGRAM - datagram (conn.less) socket
82 * @SOCK_STREAM - stream (connection) socket
83 * @SOCK_RAW - raw socket
84 * @SOCK_RDM - reliably-delivered message
85 * @SOCK_SEQPACKET - sequential packet socket
86 * @SOCK_PACKET - linux specific way of getting packets at the dev level.
87 *		  For writing rarp and other similar things on the user level.
