There is currently no mechanism provided in wpa_supplicant to configure
such behavior. One possible way of implementing this would be to add a
configuration parameter to set a minimum signal strength below which the
scan result entry would be ignored. That would allow lower priority
network to be selected even if there is a higher priority network
present in the scan results with unacceptable signal strength.
