	* ioctl.c: (if_get_flags) Deal more gracefully with failure
	  of the BSD link-state SIOCGIFMEDIA ioctl, as some interfaces
	  apparently don't implement it (e.g. tun).
	  Also, make BSD link-state checking be conditional on the
	  'link-detect' interface configuration flag, as it should be.
	  Fixes bug #465.

	* rt_netlink.c: (netlink_install_filter) BPF filter to catch and
	  drop responses to zebra's own route messages.
	  (kernel_init) add BPF filter on the netlink socket.

	* lib/zebra.h: Revert previous change, no need to include
	  <net/if_media.h> here.
	* zebra/ioctl.c: If HAVE_BSD_LINK_DETECT is defined, include
	  <net/if_media.h>
	  (if_get_flags) Remove debug messages about BSD link state.
	* zebra/kernel_socket.c: (bsd_linkdetect_translate) If link state
	  is unknown, we should set the IFF_RUNNING flag.

	* 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.

	* zebra_rib.c: (nexthop_active_check) Replace if_is_up with
	  if_is_operative to solve problems with static interface
	  routes not behaving properly with link-detect.
