Well, this isn't a dhcpcd bug as far as I'm aware.
I see the same problem from my NetBSD server to a NetBSD laptop over 
the iwi(4) interface (that's wireless) but not over the bge(4) 
interface.
That leads me to suspect an issue somewhere in kernel - more than this 
I do not know.

BTW, can you test if the kernel RS/RA works outside of dhcpcd to rule 
out dhcpcd being in error?

Thanks
