Currently, function to check if beacon countdown is complete uses deflink
to fetch the beacon and check the counter. However, with MLO, there is
a need to check the counter for the beacon in a particular link.
Add support to use link_id in order to fetch the beacon from a particular
link data.

Currently, whenever AP link is brought down via ieee80211_stop_ap()
function, all stations connected to the sdata are flushed. However, in case
of MLO there is a requirement to flush only stations connected to that link
and not all.
For instance - Consider 2 GHz and 5 GHz are AP MLD. Now due to some reason
5 GHz link of this AP is going down (link removal or any other case). All
stations connected, even legacy stations connected to 2 GHz link AP would
also be flushed. Flushing of other link stations is not desirable.
Fix this issue by passing self link ID to sta_flush() function. This would
then only remove the stations which are still using the passed link
ID as their link sta. Other stations will not be affected.

Whenever sta_flush() function is invoked, all STAs present in that
interface are flushed. In case of MLO, it is desirable to only flush such
STAs that are at least using a given link id as one of their links.
Add support for this by making change in the __sta_info_flush API argument
to accept a link ID. And then, only if the STA is using the given link as
one of its links, it would be flushed.

The new Wi-Fi Standard (IEEE Std 802.11-2020 9.4.2.160) specifies that
the Wide Bandwidth Channel Switch (WBCS) Element subfields have the same
definitions as VHT operation information if the operating band is not
S1G.
The problem comes when the BSS is in 6 GHz band, the STA parses the WBCS
Element by ieee80211_chandef_vht_oper(), which checks the capabilities for
HT/VHT mode, not HE/EHT mode.
This patch refactors STA CSA parsing flow so that the corresponding
capabilities can be checked. Also, it adds the way to use op_class in ECSA
Element to build a new chandef.
In summary, the new steps for STA to handle CSA event are:
1. build the new chandef from one of the CSA-related (Sub)Elements in
following order,
- Bandwidth Indication (Sub)Element
- Wide Bandwidth Channel Switch (Sub)Element
- Operating class in Extended Channel Switch Announcement Element
- Channel Switch Announcement Element
2. convert the new chandef into operation information according to the
operating band in order to check if the new chandef fits STA's
capabilities.
3. downgrade the bandwidth until current bandwidth is not disabled.

Some drivers may (notably mt76 does) not set up sband->band
before registering, and cfg80211 will fill it in later. But
since the HT/HE capability check mac80211 required it to be
initialized already, otherwise failing things. This really
isn't necessary though since the code is iterating the list
of bands, and has the 'band' variable available. Fix it to
not require the sband->band to be initialized already.

If intending to associate with a lower bandwidth, remove capabilities
related to 320 MHz from the EHT capabilities element. Also change the
EHT MCS-NSS set accordingly: if just reducing 320->160 or similar the
format doesn't change, just cut off the last bytes. If changing from
higher bandwidth to 20 MHz only EHT STA, adjust the format.
Note that this also requires adjusting the caller in mlme.c since the
data written can now be shorter than it determined. We need to clean
all that up. Since the other callers pass NULL for the conn limit, we
don't need to change things there.

Aloka originally suggested that puncturing should be part of

disagreed and it ended up not part of the chandef, but I've
now realized that this was wrong. Even for clients, the RX,
and perhaps more importantly, CCA configuration needs to take
puncturing into account.
Move puncturing into the chandef, and adjust all the code
accordingly. Also add a few tests for puncturing in chandef

EHT requires that stations are able to participate in
wider bandwidth OFDMA, i.e. parse downlink OFDMA and
uplink OFDMA triggers when they're not capable of (or
not connected at) the (wider) bandwidth that the AP
is using. This requires hardware configuration, since
the entity responsible for parsing (possibly hardware)
needs to know the AP bandwidth.
To support this, change the channel request to have
the AP's bandwidth for clients, and track that in the
channel context in mac80211. This means that the same
chandef might need to be split up into two different
contexts, if the APs are different. Interfaces other
than client are not participating in OFDMA the same
way, so they don't request any AP setting.
Note that this doesn't introduce any API to split a
channel context, so that there are cases where this
might lead to a disconnect, e.g. if there are two
client interfaces using the same channel context, e.g.
both 160 MHz connected to different 320 MHz APs, and
one of the APs switches to 160 MHz.
Note also there are possible cases where this can be
optimised, e.g. when using the upper or lower 160 Mhz,
but I haven't been able to really fully understand the
spec and/or hardware limitations.
If, for some reason, there are no hardware limits on
this because the OFDMA (downlink/trigger) parsing is
done in firmware and can take the transmitter into
account, then drivers can set the new flag
IEEE80211_VIF_IGNORE_OFDMA_WIDER_BW on interfaces to
not have them request any AP bandwidth in the channel
context and ignore this issue entirely. The bss_conf
still contains the AP configuration (if any, i.e. EHT)
in the chanreq.

In the channel context code we have quite a few instances
of nested loops iterating the interfaces and then links.
Add a new for_each_sdata_link() macro and use it. Also,
since it's easier, convert all the loops and a few other
places away from RCU as we now hold the wiphy mutex
everywhere anyway.
This does cause a little bit more work (such as checking
interface types for each link of an interface rather than
not iterating links in some cases), but that's not a huge
issue and seems like an acceptable trade-off, readability
is important too.

For channel contexts, mac80211 currently uses the cfg80211
chandef struct (control channel, center freq(s), width) to
define towards drivers and internally how these behave. In
fact, there are _two_ such structs used, where the min_def
can reduce bandwidth according to the stations connected.
Unfortunately, with EHT this is longer be sufficient, at
least not for all hardware. EHT requires that non-AP STAs
that are connected to an AP with a lower bandwidth than it
(the AP) advertises (e.g. 160 MHz STA connected to 320 MHz
AP) still be able to receive downlink OFDMA and respond to
trigger frames for uplink OFDMA that specify the position
and bandwidth for the non-AP STA relative to the channel
the AP is using. Therefore, they need to be aware of this,
and at least for some hardware (e.g. Intel) this awareness
is in the hardware. As a result, use of the "same" channel
may need to be split over two channel contexts where they
differ by the AP being used.
As a first step, introduce a concept of a channel request
('chanreq') for each interface, to control the context it
requests. This step does nothing but reorganise the code,
so that later the AP's chandef can be added to the request
in order to handle the EHT case described above.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

In the code we currently check for support 80+80, 160
and 320 channel widths, but really the way this should
be (and is otherwise) handled is that we compute the
highest channel bandwidth given there, and then cut it
down to what we support. This is also needed for wider
bandwidth OFDMA support.
Change the code to remove this limitation and always
parse the highest possible channel width.

Rewrite the station-side connection handling. The connection
flags (IEEE80211_DISABLE_*) are rather confusing, and they're
not always maintained well. Additionally, for wider-bandwidth
OFDMA support we need to know the precise bandwidth of the AP,
which is currently somewhat difficult.
Rewrite this to have a 'mode' (S1G/legacy/HT/...) and a limit
on the bandwidth. This is not entirely clean because some of
those modes aren't completely sequenced (as this assumes in
some places), e.g. VHT doesn't exist on 2.4 GHz, but HE does.
However, it still simplifies things and gives us a good idea
what we're operating as, so we can parse elements accordingly
etc.
This leaves a FIXME for puncturing, this is addressed in a
later patch.

Most devices now do duration calculations, so we don't hit
this code at all any more. Clearly the approach of warning
at compile time here when new bands are added didn't work,
the new bands were just added with "TODO". Clean it up, it
won't matter for new bands since they'll just not have any
need to calculate durations in software.
While at it, also clean up and unify the code a bit.

Not sure how this happened or how nothing complained, but
this variable already exists in the outer function scope
with the same value (and the SKB isn't changed either.)
Remove the extra one.

This got unused when the tracing was converted to dynamic
strings, so the define can be removed.

There are some changes coming to wireless-next that will
otherwise cause conflicts, pull wireless in first to be
able to resolve that when applying the individual changes
rather than having to do merge resolution later.

The set_active_links API is intended for link switching, so switching
to no links at all is not supported.
Add a warning to check that.

It doesn't make sense to return BSS change flags in an int, as
they're a bigger type. For this particular function it still
works OK, but clean it up to avoid future errors (or copying
this code in a broken way.)

Even if there are a lot of possible ways drivers might
call this, at least knowing when they do and with what
settings can be useful. Add tracing for it.

On the 6 GHz band, probe responses are sent as broadcast to
optimise medium usage. However, without OCE configuration
we weren't accepting them, which is wrong, even if wpa_s is
by default enabling OCE. Accept them without the OCE config
as well.

There's a call to drv_mgd_prepare_tx() and so there should
be one to drv_mgd_complete_tx(), but on this path it's not.
Add it.
