In 60g, you have new ah-hoc network type, PBSS, that should be used for P2P (spec mandates it)
In PBSS, there is AP-like entity called PCP. Instead of P2P GO negotiation, GO choosen before,
on lower layer, when selecting PCP. In this decision, "best suitable" candidate selected PCP,
based on "PCP factor" calculated for each peer. Most significant bit there is "power" since
one who is AC powered is better candidate.

Bottom line - this is to elect as P2P GO AC-powered one (if there is such peer).

Thanks, Vladimir
