wpa_supplicant select_network() relies on fast_associate to reuse old
scan results. However, this approach does not apply in some cases in
Android:
1 - If the selected network is hidden, and the SSID is in Chinese,
Android switches between fallback SSIDs, necessitating a new scan for
switching between different hidden SSIDs.
2 - Similarly, if the selected SSID is OWE (Opportunistic Wireless
Encryption), and the OWE SSID bands have been changed, select_network()
requires a fresh scan to discover hidden OWE SSIDs.
To address these, enhance select_network() to trigger new scans instead
of relying on fast_associate. This improves network selection behavior
in Android.

Add a new QCA command QCA_NL80211_VENDOR_SUBCMD_USD and related
attributes to support Unsynchronized Service Discovery (USD).
Device in active subscriber role sends SDF frames with service
information to find devices that advertise or publish the required
services. Device address, operation type, instance id, service_id,
channel info, service specific info, element container attribute, and
timeout are sent to the driver to initiate USD publish or USD subscribe
operation. The driver sends QCA_NL80211_VENDOR_SUBCMD_USD event with
instance_id and the USD operation status. QCA_NL80211_VENDOR_SUBCMD_USD
is also used to update publish operation and to cancel the publish or
subscribe operation for a service. It also allows all the operations to
be terminated using the USD flush command.

In the hostapd_cleanup_driver() function, the NULL check for the driver
private data (drv_priv) is located within the CONFIG_IEEE80211BE feature
flag. As a result, on platforms where CONFIG_IEEE80211BE is not defined,
driver->hapd_deinit(drv_priv) is called with drv_priv set to NULL. This
leads to a null pointer exception in wpa_driver_nl80211_deinit().
To address this issue, move the NULL check for drv_priv outside the
CONFIG_IEEE80211BE build flag. This ensures that the check is performed
regardless of the value of CONFIG_IEEE80211BE, preventing the NULL
pointer exception.

I've run into a case where I can bring a 2.4 GHz AP up without it being
in a bridge while I used the 'bridge=' config option. This happens when
the HT scan needed for 40 MHz operation failed to start from the get go
because another dev on the same phy was already in a scan. At the end
the AP is up and running but not added into any bridge.
Upon looking at the code, it seems that some hardware fails to issue a
scan while in AP and thus we have a fallback that switches the interface
from AP to STA before retrying another scan (it will change it back to
AP later on when finished). As we cannot have a (non-WDS) STA in a
bridge, during that procedure, we also remove/add the AP/STA from/to the
bridge as needed.
However, in wpa_driver_nl80211_scan() we do not set
drv->ap_scan_as_station until the end of the switch-to-sta &
retry-scan-start block. This means that when the recursive call to
wpa_driver_nl80211_scan() fails (the hardware is busy in my case) we
restore the interface to AP with wpa_driver_nl80211_set_mode() but that
will not add it back to the bridge. Problem.
To fix this lets always set drv->ap_scan_as_station before calling
wpa_driver_nl80211_set_mode(). In case wpa_driver_nl80211_set_mode() or
wpa_driver_nl80211_scan() fails lets call nl80211_restore_ap_mode() that
will set the mode back to AP but also handle the bridge thing as needed.

The USD passive subscriber and solicited transmission only publisher
require receiving multicast NAN action frames in order to work.
Currently, we are not requesting to receive multicast when
registering NAN action frames. As a result, USD passive subscribe or
solicited only publish may not work.
The NL80211_ATTR_RECEIVE_MULTICAST attribute corresponds to wiphy
ext feature NL80211_EXT_FEATURE_MULTICAST_REGISTRATIONS, which
requires driver support and only a few drivers in the kernel tree
support it. Namely ath9k, ath9k_htc, ath10k and hwsim. We should
fall back to register non multicast action frames if the driver
has no support.
It was confirmed that ath9k_htc starts to work after the changes.
Note that even without requesting to receive multicast Action
frames, some drivers would still upload them. For example, rtl8192cu
and hwsim. This is why test cases like test_nan_usd_match would not
fail.

Currently, when the ACS is updating the puncturing bitmap, the function
acs_update_puncturing_bitmap() sets the primary channel bitmap to 0.
This leads to a potential issue where the primary channel could be
punctured if ACS selects a different best channel within the same
segment.
To fix this issue, ensure that the primary channel bitmap is correctly
set by calculating the index of the primary channel based on the
frequency difference between the current channel and the best channel in
the segment, and is then passed to acs_update_puncturing_bitmap().
