After looking at the code (include/linux/socket.h):
#define AF_INET         2       /* Internet IP
Protocol         */

include/linux/in.h:
  IPPROTO_UDP = 17,             /* User Datagram
Protocol               */

Why 2/17 (which is AF_INET/IPPROTO_UDP) not 
registered ?

Looking at the register code: net/sunrpc/xprtsock.c:
static int __init init_xs_transport(void)
{
        xprt_register(&xs_udp4_type);
#if defined(CONFIG_IPV6) ||
defined(CONFIG_IPV6_MODULE)
        xprt_register(&xs_udp6_type);
#endif
        xprt_register(&xs_tcp4_type);
#if defined(CONFIG_IPV6) ||
defined(CONFIG_IPV6_MODULE)
        xprt_register(&xs_tcp6_type);
}

The above code must add to "xprt_list". Note that,
I configured my kernel with CONFIG_IPV6.
