RTF_ANNOUNCE was defined as RTF_PROTO2. The flag is used to indicated that host should act as a proxy for a link level arp or ndp request. (If RTF_PROTO2 is used as an experimental flag (as advertised), various problems can occur.) This commit provides a first-class definition with its own bit for RTF_ANNOUNCE, removes the old aliasing definitions, and adds support for the new RTF_ANNOUNCE flag to netstat(8) and route(8)., Also, remove unused RTF_ flags that collide with RTF_PROTO1: netinet/icmp6.h defined RTF_PROBEMTU as RTF_PROTO1 netinet/if_inarp.h defined RTF_USETRAILERS as RTF_PROTO1 (Neither of these flags are used anywhere. Both have been removed to reduce chances of collision with RTF_PROTO1.) Figuring this out and the diff are the work of Beverly Schwartz of BBN. (Passed release build, boot in VM, with no apparently related atf failures.) Approved for Public Release, Distribution Unlimited This material is based upon work supported by the Defense Advanced Research Projects Agency and Space and Naval Warfare Systems Center, Pacific, under Contract No. N66001-09-C-2073.
