dhcpcd-discuss

I disabled LAG/LACP, so there's only a real physical lan0 - I'm still
seeing the same behavior regarding routes.... but now I do see
advertisements in that tcpdump (and the dhcpcd log), but still no default
route added by dhcpcd.

However, that matches my earlier logs.. perhaps something else changed when
I added the bonding option to my kernel.  Since my old logs don't show
dhcpcd setting a default ipv6 route, my guess is that I was relying on the
kernel-native accept_ra setting.  I noticed that for some reason
net.ipv6.conf.wan0.accept_ra = 2.  2 seems to be 'always accept router
advertisements', but I tried setting it to 1 'accept if forwarding is not
enabled', and basically immediately the default route was populated.

As for not seeing the advertisement packets at all when LAG/LACP was
enabled, that looks like a firmware bug in my modem.  If the modem side has
LAG/LACP enabled, but the router side doesn't, ipv4 was working fine, but I
still didn't see the advertisement packets.  Once I disabled LAG/LACP on
the modem, the packets started showing up.

If accept_ra is set to 1 or 2, does dhcpcd not handle the default route to
avoid two processes handling the same task?
