Ah, I see. No, my laptop doesn't seem to be sending router solicitation
messages, even though the relevant sysctls are set to their default
values. I'm running Arch Linux on kernel 4.6.4, using systemd-networkd
to configure the interface.

It may be that there's some timing issues with the connection not being
available even though the interface appears to be up from the kernel's
point of view. Haven't been able to see any router solicitations go out
at all, though.

Aha, and there appears to be a systemd bug opened on this:
https://github.com/systemd/systemd/issues/3664 -- will investigate
further... thanks for the pointer :)
