It is possible for a scan to fail to see Probe Response or Beacon frame
under heavy load (e.g., during a parallel-vm.sh test run) since the
dwell time on a chanenl is quite short. Make the test cases using
INTERWORKING_SELECT more robust by trying again if the first attempt
does not find a matching BSS.

The previous check for dl_list_len() or having an entry from the list is

Extend the minimal HT 20/40 co-ex support to include dynamic changes
during the lifetime of the BSS. If any STA connects to a 2.4 GHz AP with
40 MHz intolerant bit set then the AP will switch to 20 MHz operating

If for a period of time specified by OBSS delay factor and OBSS scan
interval AP does not have any information about 40 MHz intolerant STAs,
the BSS is switched from HT20 to HT40 mode.

There could be pending unsolicited event messages on the monitor socket
when the DETACH command is issued. As such, the response may be
something else then OK even if the actual detach operation succeeded.
Try to avoid this be dropping pending messages before issuing the detach
command. As an additional workaround, check the response against FAIL
instead of requiring OK so that the self.attached does not get left to
True incorrectly even if an additional event message were to be
received.

Previously, the frequency conflict was handled only during the
association flow. However, some drivers, e.g., mac80211 based
drivers, will fail an authentication request in case that there
are no available channels for use (as they might be used by
other interfaces), and thus the frequency conflict resolution
is never called.
Fix this by calling frequency conflict resolution during
authentication (SME-in-wpa_supplicant) as well.
In addition, get the shared radio frequency from the wpa_s context in
both the SME-in-driver and SME-in-wpa_supplicant cases and not from the
driver.

The normal scan counter is used to trigger a few normal scans before a
scheduled scan is issued. The reason for doing this is that we get
results faster and some drivers support more SSIDs per normal scan
than during sched scan. After 2 normal scans, we start using
sched_scan. But the problem is that when a connection succeeds, we do
not reset this counter, so we will keep using sched scans.
To fix this, now we reset the counter when we switch to WPA_COMPLETED
state.

Sometimes function hostapd_is_dfs_required() returns -1 which indicates

IEEE80211A and when DFS support is not available (ieee80211h not set).

The P2P redirection for SAVE_CONFIG issued on the global control
interface was preventing wpas_global_ctrl_iface_save_config() from being
reached. The global version of SAVE_CONFIG was supposed to try to save
configuration files for all interface rather than just the P2P
management interface, so fix this by removing the unneeded and undesired
redirection.
Modify the global SAVE_CONFIG handler to return FAIL if no configuration
files were saved. This makes the behavior match with the per-interface
SAVE_CONFIG.
