We currently track whether we're associated and which the
BSS is in the same variable (ifmgd->associated), but for
MLD we'll need to move the BSS pointer to be per link,
while the question whether we're associated or not is for
the whole interface.
Add ifmgd->assoc_bss that stores the pointer and change
ifmgd->associated to be just a bool, so the question of
whether we're associated can continue working after MLD
rework, without requiring changes, while the BSS pointer
will have to be changed/used checked per link.

Since we always track the BSSID there when we get associated,
these are equivalent, but ifmgd->bssid saves a dereference and
thus makes the code a bit smaller, and more readable.

Currently MBSSID parameters in struct ieee80211_bss_conf
are not reset upon connection. This could be problematic
with some drivers in a scenario where the device first
connects to a non-transmit BSS and then connects to a
transmit BSS of a Multi BSS AP. The MBSSID parameters
which are set after connecting to a non-transmit BSS will
not be reset and the same parameters will be passed on to
the driver during the subsequent connection to a transmit
BSS of a Multi BSS AP.
For example, firmware running on the ath11k device uses the
Multi BSS data for tracking the beacon of a non-transmit BSS
and reports the driver when there is a beacon miss. If we do
not reset the MBSSID parameters during the subsequent
connection to a transmit BSS, then the driver would have
wrong MBSSID data and FW would be looking for an incorrect
BSSID in the MBSSID beacon of a Multi BSS AP and reports
beacon loss leading to an unstable connection.
Reset the MBSSID parameters upon every connection to solve this
problem.

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.
With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.
To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.
For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.
For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.
Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.
Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

Currently in case of target hardware restart, we just reconfig and
re-enable the security keys and enable the network queues to start
data traffic back from where it was interrupted.
Many ath10k wifi chipsets have sequence numbers for the data
packets assigned by firmware and the mac sequence number will
restart from zero after target hardware restart leading to mismatch
in the sequence number expected by the remote peer vs the sequence
number of the frame sent by the target firmware.
This mismatch in sequence number will cause out-of-order packets
on the remote peer and all the frames sent by the device are dropped
until we reach the sequence number which was sent before we restarted
the target hardware
In order to fix this, we trigger a sta disconnect, in case of target
hw restart. After this there will be a fresh connection and thereby
avoiding the dropping of frames by remote peer.
The right fix would be to pull the entire data path into the host
which is not feasible or would need lots of complex changes and
will still be inefficient.
Tested on ath10k using WCN3990, QCA6174

When we get anti-clogging token required (added by the commit
mentioned below), or the other status codes added by the later
commit 4e56cde15f7d ("mac80211: Handle special status codes in
SAE commit") we currently just pretend (towards the internal
state machine of authentication) that we didn't receive anything.
This has the undesirable consequence of retransmitting the prior
frame, which is not expected, because the timer is still armed.
If we just disarm the timer at that point, it would result in
the undesirable side effect of being in this state indefinitely
if userspace crashes, or so.
So to fix this, reset the timer and set a new auth_data->waiting
in order to have no more retransmissions, but to have the data
destroyed when the timer actually fires, which will only happen
if userspace didn't continue (i.e. crashed or abandoned it.)

For admission control, obviously all of that only works for
QoS data frames, otherwise we cannot even access the QoS
field in the header.
Syzbot reported (see below) an uninitialized value here due
to a status of a non-QoS nullfunc packet, which isn't even
long enough to contain the QoS header.
Fix this to only do anything for QoS data packets.

Submitting AP probe/null during suspend can cause unexpected
disconnect on resume because of timeout waiting for ack status:
wlan0: Failed to send nullfunc to AP 11:22:33:44:55:66 after 500ms, disconnecting
This is especially the case when we enter suspend when a scan is
ongoing, indeed, scan is cancelled from __ieee80211_suspend, leading
to a corresponding (aborted) scan complete event, which in turn causes
the submission of an immediate monitor null frame (restart_sta_timer).
The corresponding packet or ack will not be processed before resuming,
causing a timeout & disconnect on resume.
Delay the AP probing when suspending/suspended.

[remove now unnecessary size validation, use -ENOMEM, free elems earlier

As the 802.11 spec evolves, we need to parse more and more
elements. This is causing the struct to grow, and we can no
longer get away with putting it on the stack.
Change the API to always dynamically allocate and return an
allocated pointer that must be kfree()d later.
As an alternative, I contemplated a scheme whereby we'd say
in the code which elements we needed, e.g.
DECLARE_ELEMENT_PARSER(elems,
SUPPORTED_CHANNELS,
CHANNEL_SWITCH,
EXT(KEY_DELIVERY));
ieee802_11_parse_elems(..., &elems, ...);
and while I think this is possible and will save us a lot
since most individual places only care about a small subset
of the elements, it ended up being a bit more work since a
lot of places do the parsing and then pass the struct to
other functions, sometimes with multiple levels.

We have mgd_prepare_tx(), but sometimes drivers may want/need
to take action when the exchange finishes, whether successfully
or not.
Add a notification to the driver on completion, i.e. call the
new method mgd_complete_tx().
To unify the two scenarios, and to add more information, make
both of them take a struct that has the duration (prepare only),
subtype (both) and success (complete only).

All uses of ieee80211_get_he_sta_cap() were actually wrong,
in net/mac80211/mlme.c they were wrong because that code is
also used for P2P (which is a different interface type), in
net/mac80211/main.c that should check all interface types.
