Print undecoded NFS handles

"-u" option is used to print undecoded NFS handles, and the code is here:

......
if (ndo->ndo_uflag) {
	u_int i;
	char const *sep = "";

	ND_PRINT(" fh[");
	for (i=0; i<len; i++) {
		/*
		 * This displays 4 bytes in big-endian byte
		 * order.  That's as good a choice as little-
		 * endian, as there's no guarantee that the
		 * server is big-endian or little-endian or
		 * that the file handle contains 4-byte
		 * integral fields, and is better than "the
		 * byte order of the host running tcpdump", as
		 * the latter means that different hosts
		 * running tcpdump may show the same file
		 * handle in different ways.
		 */
		ND_PRINT("%s%x", sep, GET_BE_U_4(dp + i));
		sep = ":";
	}
	ND_PRINT("]");
	return;
}
