Add test cases to test basic cohosted MLDs functionality. Add helper
functions to create the configuration file, start hostapd instance.
Client connectivity test case will be added via a subsequent commit.
eht_mld_cohosted_discovery: 2 co-hosted MLDs without non-MLD RNR. Basic
bring up and beacon, MLD RNR, scan validation.
eht_mld_cohosted_discovery_with_rnr: Same like eht_mld_cohosted_discovery
but additionally non-MLD RNR (rnr=1) is also enabled. Validate the non-MLD
RNR as well.

When AP is beaconing only on the 6 GHz band and unsol_bcast_presp
interval is set, AP sends unsolicited broadcast Probe Response frames
for in-band discovery. hostapd sent the Probe Response template for this
frame only when setting a new Beacon frame template.
Extend this to update the Probe Response template during BSS color

This is needed to match the implementation change to map the 5 GHz
channels 149-175 to the global operating class 125 instead of 124.
Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
According to IEEE Std 802.11-2020, Operating classes Table E-2 (Europe)
and Table E-6 (China) map channels in the range 149 to 161 to the global
operating class 125, while Table E-1 (United States) maps these channels
to global operating classes 125 and 124 as well. The global operating
class 125 contains all channels from the global operating class 124 and
some additional channels.
Hence, to make the selection of the current operating class generic, use
operating class 125 for all 20 MHz channels in the range 149 to 161.

If a non-PSC 6 GHz channel with bandwidth higher than 20 MHz is
configured, duplicate beacons/FD/UBPR will be transmitted in other 20
MHz channels of the current configured bandwidth to aid in faster scan.
In such cases the duplicate FD needs to carry the Operating Class and
Primary Channel subfields for non-AP STAs to identify the primary
non-PSC.
IEEE Std 802.11-2020, 9.6.7.36 (FILS Discovery frame format):
"The Operating Class subfield specifies the operating class of the
Primary Channel of the transmitting AP (see 9.4.1.36).
The Primary Channel subfield is set to the channel number of the primary
channel (see 11.15.2) if the FILS Discovery frame is transmitted as a
non-HT duplicate PPDU; otherwise, the subfield is not present."
Hence, add the Operating Class and Primary Channel subfields if the
current channel is non-PSC and the channel bandwidth is 40 MHz or
higher.

Add a new QCA vendor subcommand QCA_NL80211_VENDOR_SUBCMD_AP_SUSPEND to
allow suspend and resume the AP interface. When an AP is suspended, it
disconnects all connected clients and stops all TX/RX operations on the
AP interface. The driver retains the AP configuration and on resume, all
AP operations are resumed with the same configuration.
This subcommand is also used in the event path to notify userspace about
AP suspended or resumed state changes.
This uses attributes defined in enum qca_wlan_vendor_attr_ap_suspend.

Previously, MLO Link KDE was added only for each link that was
negotiated for the ML association. However, IEEE Std 802.11be/D5.0,

AP" which is not constrained by what the non-AP MLD might have requested
or what the negotiation outcome for this particular ML association is.

When the RADIUS response included a Session-Timeout attribute, but is
otherwise valid (an Access-Accept with a valid Tunnel-Password), the
association still failed due to the strict comparison of the accepted
value with HOSTAPD_ACL_ACCEPT. Apparently this combination wasn't
previously tested.
Extend this to allow a packet containing a valid Session-Timeout
attribute to be accepted by extending the "success" comparison to
include HOSTAPD_ACL_ACCEPT_TIMEOUT.

If the TX success response races with the RX frame then the state
machine was simply move to P2P_SD_DURING_FIND to continue the operation.
However, this does not take into account broadcast queries where the
callback handler updates the peer's sd_pending_bcast_queries.
Fix this by exporting the callback and calling it directly. This is
fine, as the operation is cancelled immediately afterwards, ensuring
that the callback is not called a second time.

RNR formation for co-location or MLO did not work as expected. Fix this.
For example, during co-location, if the BSS is also its ML partner
there is no need to include a separate TBTT for it.
Also, during co-location, if the BSS is not its partner but it is ML
capable, the TBTT length should be 16 bytes and it should include the
MLD Parameters for it in the RNR.
During co-location, for a given Neighbor AP (operating on a given
channel and op-class) if it has BSSs which are ML capable as well as
BSSs which are not, there should be two Neighbor AP Info present: one
indicating TBTT length as 13 bytes and one indicating TBTT info length
as 16 bytes.

Whenever a BSS was set up,hostapd flushed all stations via the flush()
driver operation which maps to NL80211_CMD_DEL_STATION in the nl80211
interface. However, in case of MLO, a station could have been connected
to other links by the time this link is coming up. Since link ID was not
passed to flush(), all those stations entries were also removed in the
driver which is wrong.
Include the link ID along with the command in AP MLD so that the driver
can use this link ID and flush only the stations that use the passed
link ID as one of their links.
