Subject: lib: treat OSX as BSD for IP_HDRINCL (BZ#739)
X-Git-Tag: frr-2.0-rc1~1763
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=3f0bfc9e82e0d735be2cb06d5c4a3028650637bf;p=matthieu%2Ffrr.git

lib: treat OSX as BSD for IP_HDRINCL (BZ#739)

Mac OS X needs HAVE_IP_HDRINCL_BSD_ORDER defined like BSD. If it's not
defined, it'll fail like this:

  *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 64,
  interface en0, mtu 1500: Invalid argument

Which is caused by reordering iph->ip_len in
sockopt_iphdrincl_swab_htosys.
