My guide here is hostapd's defconfig, where it's stated that "ACS is
currently only supported through the nl80211 driver". Search through the
source code also reveals ACS machinery in the nl80211 driver only.
hostapd builds successively with ACS enabled and nl80211 disabled, but
an attempt to use ACS by setting a wireless channel to 0 results in a
runtime failure (driver doesn't accept this value).
