If the BSS Transition Management Request frame includes only a single
candidate and we need to scan for the BSS to get up-to-date information,
use a scan for the known BSSID instead of wildcard BSSID. In addition,
set the SSID in the scan if it is known based on old scan results in the
BSS table. This removes unnecessary Probe Response frames when we are
interested in results from only a single BSS.

This makes hostapd track Supported Operating Classes information from
the associated STAs. The stored information is available through the STA
control interface command (supp_op_classes row) as a hexdump of the
Supported Operating Classes element starting from the Length field. This
information can be used as input to BSS transition management and
channel switching decisions.

This adds parsing of non-preferred channel list on an MBO AP. The
information in (Re)Association Request and WNM Notification Request
frames is parsed to get the initial value and updates from each
associated MBO STA. The parsed information is available through the STA
control interface command non_pref_chan[i] rows.

This makes wpa_is_bss_tmp_disallowed() expire old entries from the
bss_tmp_disallowed list even if they do not match the BSSID that is
being searched for. This allows the list to be kept at shorter length to
speed up operations and minimize memory use in cases where the
previously disabled BSS is not in radio range anymore.

Add tests to verify that MBO IE in BSS Transition Management Request
frame is parsed correctly:
1. The MBO transition reason code is received by the MBO station.
2. The MBO cellular data connection preference is received by the
MBO station.
3. The MBO station does not try to connect to the AP until the retry
delay is over.

Add an option to add MBO IE to BSS Transition Management Request frame.
The MBO IE includes the transition reason code, cellular data connection
preference, and, if the disassoc imminent bit is set, it may also
include re-association retry delay. Otherwise, the re-association retry
delay should be set to zero.
The additional BSS_TM_REQ argument uses the following format:
mbo=<reason>:<reassoc delay>:<cell pref>
reason: 0-9
reassoc delay: 0-65535 (seconds; 0 = disabled)
cell pref: 0, 1, 255

Add MBO IE with AP capability attribute to Beacon, Probe Response, and
(Re)Association Response frames to indicate the AP supports MBO.
Add option to add Association Disallowed attribute to Beacon, Probe
Response, and (Re)Association Response frames. Usage:
SET mbo_assoc_disallow <reason code>
Valid reason code values are between 1-5. Setting the reason code to
0 will remove the Association Disallowed attribute from the MBO IE
and will allow new associations.
MBO functionality is enabled by setting "mbo=1" in the config file.
