This is normal.
dhcpcd will handle receiving the RA, not the kernel.
You're not missing an option.

Can you email me the logfile please?
There might be some other error in there.

What are x-apple-data-detectors? Maybe that's confusing dhcpcd, but it

Can you also email a binary capture of that please?

tcpdump -w/tmp/cap -s0 icmp6

and email me /tmp/cap
