What I want to do is something like:

slaac private
interface p2p-wlan*
  slaac hwaddr

The reason for that is that it is convenient for p2p interfaces to be able to derive the local-link address from the MAC, but I don't need it for any other interface.

I might be missing something, but I don't think that there's an easy way of doing something along those lines? Sorry if I missed it or so.
