There are many dualband APs with 2.4 and 5 GHz radios configured with
the same network. This is why the hostapd default behavior manages the
WPS operations consistently on the radios. wps_independent=1 can be used
in a per-BSS configuration to separate a subset of BSSes into their own
independent "WPS group".
