请问socket中type的SOCK_RAW和SOCK_PACKET有什么区别?

rt,thx.

       In  Linux  2.0,  the  only  way  to  get a packet socket was by calling
       socket(AF_INET, SOCK_PACKET, protocol).  This is  still  supported  but
       strongly  deprecated.   The  main difference between the two methods is
       that SOCK_PACKET uses the old struct sockaddr_pkt to specify an  inter-
       face, which doesn’t provide physical layer independence.

           struct sockaddr_pkt {
               unsigned short spkt_family;
               unsigned char  spkt_device[14];
               unsigned short spkt_protocol;
           };

       spkt_family  contains  the device type, spkt_protocol is the IEEE 802.3
       protocol type as defined in <sys/if_ether.h>  and  spkt_device  is  the
       device name as a null-terminated string, for example, eth0.

       This structure is obsolete and should not be used in new code.
