[ale] kernel: NET: Registered protocol family 17

[Jamey Owens]

Heya,

I think that ianna the references are just the decimal values used in the 
packet header to identify the protocol.

If you check out the socket.h header file in the kernel all the families are 
listed out.  Family 17 is AF_PACKET

Full list of families:
#define AF_UNSPEC       0
#define AF_UNIX         1       /* Unix domain sockets          */
#define AF_LOCAL        1       /* POSIX name for AF_UNIX       */
#define AF_INET         2       /* Internet IP Protocol         */
#define AF_AX25         3       /* Amateur Radio AX.25          */
#define AF_IPX          4       /* Novell IPX                   */
#define AF_APPLETALK    5       /* AppleTalk DDP                */
#define AF_NETROM       6       /* Amateur Radio NET/ROM        */
#define AF_BRIDGE       7       /* Multiprotocol bridge         */
#define AF_ATMPVC       8       /* ATM PVCs                     */
#define AF_X25          9       /* Reserved for X.25 project    */
#define AF_INET6        10      /* IP version 6                 */
#define AF_ROSE         11      /* Amateur Radio X.25 PLP       */

#define AF_ATMSVC       20      /* ATM SVCs                     */
#define AF_SNA          22      /* Linux SNA Project (nutters!) */
#define AF_IRDA         23      /* IRDA sockets                 */
#define AF_PPPOX        24      /* PPPoX sockets                */
#define AF_WANPIPE      25      /* Wanpipe API Sockets */
#define AF_LLC          26      /* Linux LLC                    */
