7d0c08910b More generic unsolicited broadcast Probe Response template setup
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.

As a preparation for extending this functionality to other cases, move
the generation of the unsolicited broadcast Probe Response template into
a more generic function and data structure.

b9113105ad FILS: Add Operating Class and Primary Channel in FD for non-PSC chan
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.

de1bfda64e Fix RNR building for co-location and MLO
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.

259b43a31a hostapd: MLO: Avoid use of mld_id as user configuration
mld_id was provided as a user configuration to identify partner BSS
belonging to the same AP MLD. The same id is used at the protocol level
also to indicate the AP MLD ID of the MLD.

But, in general mld_id is a relative reference of the MLD where 0 is
used as the mld_id to represent the self MLD and in case of MLO MBSSID
mld_id of a non transmitted BSS affiliated to an AP MLD is based on the
relative BSS index of the non transmitted BSS from the transmitted BSS.
Hence mld_id need not be fetched from users, rather it can be identified
wherever required.

To verify if the partners belong to the same AP MLD the interface name
can be checked, since all link BSS partners of the same AP MLD belong to
the same interface.

Hence, remove use of mld_id user config and instead introduce two
functions hostapd_is_ml_partner() and hostapd_get_mld_id(). The former
is used to verify whether partners belong to the same AP MLD and the
latter is used to get the MLD ID of the BSS.

fc0b0cdcb9 hostapd: Avoid unnecessary Beacon frame update for co-location
When it comes to set some BSS's beacon, there are two reasons to
update the beacon of co-located hostapd_iface(s) at the same time:
1. 6 GHz out-of-band discovery
2. MLD operational parameters update

BSS load update is unrelated with the above two reasons, and therefore
is not the case to update beacon for co-location. Moreover, updating
beacon for co-location when BSS load update makes hostapd set beacon too
frequently, which makes hostapd busy setting beacon in a multi-BSS case.

Add a new function to update beacon only for current BSS and use the
function during BSS load update.

Add this support by splitting the reduced neighbor report (RNR) in as

excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will

gathered through neighbor reports.
