hrs 2eb62239d7 Improve flexibility of receiving Router Advertisement and ... automatic link-local address configuration: - Convert a sysctl net.inet6.ip6.accept_rtadv to one for the default value of a per-IF flag ND6_IFF_ACCEPT_RTADV, not a global knob. The default value of the sysctl is 0. - Add a new per-IF flag ND6_IFF_AUTO_LINKLOCAL and convert a sysctl net.inet6.ip6.auto_linklocal to one for its default value. The default value of the sysctl is 1. - Make ND6_IFF_IFDISABLED more robust. It can be used to disable IPv6 functionality of an interface now. - Receiving RA is allowed if ip6_forwarding==0 *and* ND6_IFF_ACCEPT_RTADV is set on that interface. The former condition will be revisited later to support a "host + router" box like IPv6 CPE router. The current behavior is compatible with the older releases of FreeBSD. - The ifconfig(8) now supports these ND6 flags as well as "nud", "prefer_source", and "disabled" in ndp(8). The ndp(8) now supports "auto_linklocal". Discussed with: bz and jinmei Reviewed by: bz MFC after: 3 days		2009-09-12 22:08:20 +00:00
