[link-detect] Try to get BSD link-detect to work properly.

2008-01-10 Ingo Flaschberger <if@xip.at>

	* configure.ac: Define HAVE_BSD_LINK_DETECT if <net/if_media.h> is
	  present.
	* lib/zebra.h: If HAVE_BSD_LINK_DETECT is defined,
	  include <net/if_media.h>.
	* zebra/ioctl.c: (if_get_flags) If HAVE_BSD_LINK_DETECT, use the
	  SIOCGIFMEDIA ioctl to ascertain link state.
	* zebra/kernel_socket.c: (bsd_linkdetect_translate) New function to
	  map the ifm_data.ifi_link_state value into the IFF_RUNNING flag.
	  (ifm_read) Call bsd_linkdetect_translate to fix the IFF_RUNNING
	  flag before calling if_flags_update.
