So this is a misconfiguration on the router and a bug I've just fixed in dhcpcd.
Basically you have a RA saying "DHCPv6 exists, start INFORMATION REQUEST".
However, no DHCPv6 reply comes back to our request.
We do obey the RFC timings, with a caveat - we mirror CONFIRM MAX_MD so we can 
use the last "lease" we got.
The bug here is that we reset them timings when doing this and will be fixed in 
the next version.

So as far as you are concered this is just noise in the logs.

(note, last lease for INFORM currently doesn't work anyway and I'm in two minds 
wether to fix that or not)
