[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.
