However, I think the second bullet is telling me I can only have one >AP. Is that right? If so, then is the correct interpretation of this output that the maximum number of APs I can run is one (second bullet), and the maximum of the sum of the number of APs and P2P->GOs I can have is eight, e.g. one AP + seven P2P-GO, or zero AP + eight P2P-GO.
