It would make sense to support these, but I'd need to see wpa_supplicant
debug log showing removal and re-insert sequences. In any case, I don't
think this was designed in a way that would avoid reconfiguring these
parameters for the new interface, but rather, this is something that has
not been considered in the past for this remove/re-add case.
These parameters should not really be used and they are subject to be
removed.. There are much better ways of achieving channel selection
through the control interface for P2P and these four parameters were
meant only for development time testing purposes.
