In theory, operating class could be used to negotiate channel bandwidth during GO Negotiation. In practice, though, most implementations do not do this. Instead, the device that becomes the GO can just decide to enable 40 MHz (or 80/80+80/160 MHz for VHT) on its own regardless of which operating class was used. This should still be done in a way that the primary channel ends up being where indicating during GO Negotiation to allow the P2P Client to find the GO more easily. -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
