 1.29  21-Apr-2020  wiz Remove -M from SYNOPSIS as well.
 1.28  21-Apr-2020  roy rtadvd: Remove router renumbering - it's been disable for years
 1.27  11-Nov-2019  roy rtadvd: Add C flag to control the zeroing of the leaving configuration

This is only intended to assist the testing of clients which consume
Router Advertisement messages, such as dhcpcd(8).
 1.26  06-Nov-2017  christos branches: 1.26.4; 1.26.6;
Change the meaning of the 'D' flag to print errors to stderr instead of
syslog(3) and exit if poll(2) fails (intended to be used with unit-tests).
 1.25  16-Dec-2016  ozaki-r branches: 1.25.6;
Support -p <pidfile> option

It's needed to avoid using /var/run/rtadvd.pid on ATF tests and
run multiple instances of rump.rtadvd on a test.
 1.24  13-Dec-2012  wiz branches: 1.24.12;
Formatting nit.
 1.23  13-Dec-2012  roy Remove the iflist array and store ifflags in rainfo.

Add support for SIGHUP to re-read the configuration for each interface.
If an invalid configuration is found, we continue to use the old one;
otherwise we expire the current one and then start advertising the new one.

Specififed interfaces don't have to exist at startup.
If specified interfaces arrive, load their config and start advertising.
If they depart, remove their rainfo structure and continue.

Fixes PR/43881 and PR/47311

NDP-related improvements:
RFC4191
- supports host-side router-preference

RFC3542
- if DAD fails on a interface, disables IPv6 operation on the
interface
- don't advertise MLD report before DAD finishes

Others
- fixes integer overflow for valid and preferred lifetimes
- improves timer granularity for MLD, using callout-timer.
- reflects rtadvd's IPv6 host variable information into kernel
(router only)
- adds a sysctl option to enable/disable pMTUd for multicast
packets
- performs NUD on PPP/GRE interface by default
- Redirect works regardless of ip6_accept_rtadv
- removes RFC1885-related code

KNF, fix time printing formats.

Don't start another copy of rtadvd if one is running.

PR/52618: Shinichi Doyashiki: Don't exit if adding interface to multicast
group fails. This happens with empty vlan interfaces
- make syscalls checks against -1
- fix errors to print %s: instead of <%s>
XXX: if_vlan is the only pseudo interface in net/ that returns such an
error..

Kill rtadvd surely even if the tests fail in the middle
It may help PR bin/52701.

Change the meaning of the D flag to print errors to stderr instead of
syslog(3) and exit if poll(2) fails (intended to be used with unit-tests).

Mark expandm as preserving format strings.

Let rtadvd not use syslog for logging
Thanks to christos@ now rtadvd can log via stderr instead of syslog
by -D option.

rtadvd: Fix reloading configuration killing interface timers

rtadvd: remove support for SIOCSIFINFO_IN6
It's been broken since we enabled dropping privs.
It's also probably the wrong place to do this, and support for
SIOCSIFINFO_IN6 will be in the next dhcpcd import.

rtadvd: Add C flag to control the zeroing of the leaving configuration
This is only intended to assist the testing of clients which consume
Router Advertisement messages, such as dhcpcd(8).
