	* irdp_packet.c: (parse_irdp_packet) style issues.
	  Use sockopt_iphdrincl_swab_systoh.
          Try unbork the code. Checksum the ICMP data and actually
          compare it to received checksum. Check data length against
          claimed length in header.
	  Always use ntoh.. when accessing addresses, even when the
          comparison happens to be endian-safe.
	  (send_packet) minor style isues. Use
          sockopt_iphdrincl_swab_htosys.
	  (irdp_iph_hton/ntoh) IP header to/from network/host order.
