The nl80211 driver interface function mlme_event_mgmt_tx_status(),
filled in link_id only if the frame was the last transmitted on the
whole drv (driver) level. With co-hosted MLDs, there could be cases
where multiple frames are sent out by various interfaces (BSS) under the
same drv. Now while handling the TX status, only one interface will get
the proper link_id. Rest will get -1 and the event will be routed to the
first BSS always. If the frame was not sent from the first BSS this
leads to possibility of the frame getting dropped.
Hence to make the underlying link identification easier, modify
authentication and association frames to be always sent with the link
address as A1 and A3 for ease of TX status handling.

If authentication fails repeatedly, e.g., because of a weak signal, the
link can end up in blocked state. If one of the nodes tries to establish
a link again before it is unblocked on the other side, it will block the
link to that other side. The same happens on the other side when it
unblocks the link. In that scenario, the link never recovers on its own.

Previously, hostapd directly advertised the MLD capabilities received
from the driver. Since this information is exchanged during
initialization time only, the driver will advertise the maximum
supported values. hostapd should parse it and then based on the current
situation fill the values accordingly.
For example, the maximum number of simultaneous links is supposed to be
a value between 0 and 14, which is the number of affiliated APs minus 1.
The driver advertises this value as 5 and hostapd, irrespective of the
current active links, puts 5 in the frames.

Currently, whenever a new BSS is created, if it is an EHT BSS it is tied
to a corresponding MLD structure. If the structure does not exist
already, a new one is created and tied to it. Accordingly, the link ID
is assigned as well. However, when the BSS is deleted, the MLD structure
is not freed and when it is again created the next time, the link ID is
incremented further and the BSS gets a wrong link ID.
For example, 2.4 GHz single link AP MLD case: First ADD, link ID 0 would
be assigned and MLD interface wlan0 would be created. When REMOVE is
issued, the BSS would be deleted but MLD wlan0 will not. When ADD is
issued again, the BSS will tie back to MLD wlan0 but this time the link
ID will be incremented again and 1 would be assigned. Hence, at
subsequent REMOVE/ADD, the link ID keeps on incrementing.
Since the link ID remains same for the full lifetime of the BSS and MLD,
the next link ID counter cannot be just reset back to 0 when a BSS is
deleted. Otherwise, in interleaved link enable/disable case, the link ID
would be changed.
To overcome this situation, whenever a BSS is deleted, if the MLD is not
referenced by any other existing BSS, delete the MLD structure itself.
To know how many BSSs are referring a given MLD, introduce a new member
refcount in MLD. If the value is 0 it is safe to delete the MLD.

Link ID was assigned when BSS is going through setup and the driver
interface init. Later if interface is disabled and enabled again, setup

Hence, assign the link ID during BSS creation itself. And it will remain
until BSS entry is completely freed. Hence, link ID will not change as
part of disable/enable.
Also, since link ID would be decided now, it will help in creating link

scale.

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

the correct way of encoding the special cases, i.e., 80+80 MHz channels
that use two nonadjacent frequency segments.
Add support for encoding the 80+80 MHz channel with the 2-octet
operating class design using the Operating Class Duple sequence field of
the Supported Operating Classes element instead of listing the operating
classes that have the 80+ behavior limit set indication in Table E-4
(i.e., opclass 130 and 135) as 1-octet operating classes in the
Operating Classes field.

Commit 085a3fc76e ("EHT: Add 320 channel width support") added this in
various places, but it did not cover everything. Extend this support to
be more complete. In particular, this allows wpa_supplicant to report
the operating class 137 in the Supported Operating Classes element and
to use it when processing beacon requests.

short_ssid in the own neighbor report might get out of sync, causing
advertising RNR element based on the old SSID, when SSID is changed
either with control interface command SET or with SIGHUP. Therefore,
sync the own report entry by removing the old entry and setting own
report again if the short SSID value has changed.

Once the non-AP MLD is added to the driver, the driver handles the
address translation so that hostapd receives Management frames with
SA/DA being translated into MLD MAC addresses.
If the Authentication frmae is retransmitted with transaction being 1,
SA of the retransmitted Authentication frame is translated into the MLD
MAC address by the driver, and then in the function handle_auth(),
sta->mld_info.links[].peer_addr would be replaced by the MLD MAC address
even though it is supposed to be the link address.
Therefore, update the MLD information only when the STA has not yet been
added into the driver to avoid replacing the previously determined link
address with the MLD MAC address.

In theory, os_snprintf() could return a negative value and as such,
os_snprintf_error() should be used in all cases where the buffer might
not be large enough.
