mycroft 1afe1f83af Be much more robust with RID values during attach:
* If the device returns a length too short to even contain the RID number,
  flag it as not supported and return EOPNOTSUPP, rather than returning a
  length of -2 and trying to use the value anyway.
* Check the returned lengths to see if we actually got anything.
* If we get no rate list, fail the attach, so we don't just blow up later.
Allow the frontend to pass in a MAC address.
