+ * ospf_dump.c: (ospf_ip_header_dump) Assume header is in host order
+ remove ntohs that should have dissappeared. Take struct ip
+ as argument, caller has to know there's an IP header at start of
+ stream anyway.
+ * ospf_dump.h: update declaration of ospf_ip_header_dump.
+ * ospf_packet.c: (ospf_write) correct call to
+ sockopt_iphdrincl_swab_htosys which was munging the header.
+ (ospf_recv_packet) ip_len is needed for old OpenBSD fixup.
+ (ospf_read) sockopt_iphdrincl_swab_systoh ip header as soon as
+ we have it.
