hostapd: Fix to downgrade bandwidth in radar detection
Upon radar detection we used to search channels with the same bandwidth.
This way we might not find any other channels. If there are no channels
available with that bandwidth the AP service will be stopped. To avoid
this problem, also search a suitable channel by downgrading the
bandwidth. This scenario is applicable during CAC as well.
DFS: Do not process radar event while disabling an interface
In the normal case hostapd_disable_iface() and hostapd_enable_iface()
will be done while switching to another DFS channel upon radar
detection. In certain scenarios radar detected event can come while
hostapd_disable_iface() is in progress and iface->current_mode will be
NULL in that scenario. Previously, we did not check for this scenario
and proceeded with the radar detection logic which can trigger a
segmentation fault. To fix this, avoid proceeding the radar detection
event if iface->current_mode is NULL.
Allow wildcard SSID to be enforced for a specific BSSID scan
Specific BSSID scan was replacing wildcard SSID with the known SSID if
any BSS with the specified BSSID is available in the known BSSes list.
Add control interface support to force use of a wildcard SSID in a
specific BSSID scan by user with the new "wildcard_ssid=1" argument to
the SCAN command.
Incorrect he_enabled parameter was being passed to
hostapd_set_freq_params() in mesh which caused HE to be not fully
enabled on the 5 GHz band. Fix this by setting freq->he_enabled instead
of vht_freq.he_enabled so that the hostapd_set_freq_params() uses the
correct he_enabled value (and then ends up copying this to
vht_freq.he_enabled in the success case).

mode for extended duration (or even permanently). Such an environment
will still need to prevent wildcard AP selection with PBC since an
incorrect device could be selected. However, if the Enrollee device has
been explicitly requested to connect to a specific AP based on its

which AP would be selected (only the one matching the specified BSSID is
acceptable).
Start filtering scan results for PBC session overlap check based on the
locally specified constraint on the BSSID, if one is set. This allows

another AP device is claiming to be in active PBC mode while "WPS_PBC"
