description:
Move RTF_ANNOUNCE flag so that it no longer conflicts with RTF_PROTO2.
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.)
