    As per email discussion Jouni Malinen pointed out that:
    
    "P2P message exchanges can be executed on the current operating channel
    of any operation (both P2P and non-P2P station). These can be on 5 GHz
    and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz).
    
    As an example, it would be possible to receive a GO Negotiation Request
    frame on a 5 GHz only radio and then to complete GO Negotiation on that
    band. This can happen both when connected to a P2P group (through client
    discoverability mechanism) and when connected to a legacy AP (assuming
    the station receive Probe Request frame from full scan in the beginning
    of P2P device discovery)."
    
    This means that P2P messages can be sent over different radio devices.
    However, these should use the same P2P device address so it should be
    able to provision this from user-space. This patch adds a parameter for
    this to struct vif_params which should only be used during creation of
    the P2P device interface.
