PATCH 1/1 distinguish the inet and inet6 domain when loading the tcp_diag module

When load the tcp_diag module, and use "ss -f inet" command to show the socket information of inet domain. But this command also shows the information of inet6 domain, but not only inet domain. and "ss -f inet6", "ss -4", "ss -6" have the same problem.
