We still have ieee80211_chandef_rate_flags() and all that,
but all the users seem pretty much broken (deflink, etc.)
Remove all the code. It's been two years since last anyone
even vaguely entertained the notion of looking at this and
fixing it.

The worker really shouldn't be queued for a non-running interface.
Also, if ieee80211_setup_sdata is called between queueing and executing

Currently, ieee80211_ie_build_he_oper() lacks support for 320 MHz handling
(already noted as a TODO). This is because 320 MHz is not included in
IEEE 802.11-ax. However, IEEE 802.11-be introduces 320 MHz support and if
the chandef indicates a 320 MHz bandwidth and is used directly as it is, it
will result in an incorrect HE Operation Information Element.
In order to support EHT 320 MHz, HE Operation Element should indicate
bandwidth as 160 MHz only. In EHT Operation IE, the correct bandwidth will
be present. Devices capable of EHT can parse EHT Information Element and
connect in 320 MHz and other HE capable devices can parse HE and can
connect in 160 MHz.
Add support to downgrade the bandwidth in ieee80211_ie_build_he_oper()
during 320 MHz operation and advertise it.

If we got an unprotected action frame with CSA and then we heard the
beacon with the CSA IE, we'll block the queues with the CSA reason
twice. Since this reason is refcounted, we won't wake up the queues
since we wake them up only once and the ref count will never reach 0.
This led to blocked queues that prevented any activity (even
disconnection wouldn't reset the queue state and the only way to recover
would be to reload the kernel module.
Fix this by not refcounting the CSA reason.
It becomes now pointless to maintain the csa_blocked_queues state.
Remove it.

In case we fail to resume, we'll WARN with
"Hardware became unavailable during restart." and we'll wait until user
space does something. It'll typically bring the interface down and up to
recover. This won't work though because the queues are still stopped on

Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.
Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.
Hence, in order to support DFS with MLO, do the following changes -
* Add channel context conf pointer as an argument to the function
ieee80211_radar_detected(). During MLO, drivers would have to pass on
which channel context conf radar is detected. Otherwise, drivers could
just pass NULL.
* ieee80211_radar_detected() will iterate over all channel contexts
present and
* if channel context conf is passed, only mark that as radar
detected
* if NULL is passed, then mark all channel contexts as radar
detected
* Then as usual, schedule the radar detected work.
* In the worker, go over all the contexts again and for all such context
which is marked with radar detected, cancel the ongoing CAC by calling
ieee80211_dfs_cac_cancel() and then notify cfg80211 via
cfg80211_radar_event().
* To cancel the CAC, pass the channel context as well where radar is
detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
canceled only on the links using the provided context, leaving other
links unaffected.
This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

Currently, during starting a radar detection, no link id information is
parsed and passed down. In order to support starting radar detection
during Multi Link Operation, it is required to pass link id as well.
Add changes to first parse and then pass link id in the start radar
detection path.
Additionally, update notification APIs to allow drivers/mac80211 to
pass the link ID.
However, everything is handled at link 0 only until all API's are ready to
handle it per link.

A few members related to DFS handling are currently under per wireless
device data structure. However, in order to support DFS with MLO, there is
a need to have them on a per-link manner.
Hence, as a preliminary step, move members cac_started, cac_start_time
and cac_time_ms to be on a per-link basis.
Since currently, link ID is not known at all places, use default value of
0 for now.

This reverts commit ce9e660ef32e ("wifi: mac80211: move radar detect work to sdata").
To enable radar detection with MLO, it’s essential to handle it on a
per-link basis. This is because when using MLO, multiple links may already
be active and beaconing. In this scenario, another link should be able to
initiate a radar detection. Also, if underlying links are associated with
different hardware devices but grouped together for MLO, they could
potentially start radar detection simultaneously. Therefore, it makes
sense to manage radar detection settings separately for each link by moving
them back to a per-link data structure.

In commit 0d9c2beed116 ("wifi: mac80211: fix monitor channel
with chanctx emulation") I changed mac80211 to always have an
internal monitor_sdata to have something to have the chanctx
bound to.
However, if the driver didn't also have the WANT_MONITOR flag
this would cause mac80211 to allocate it without telling the
driver (which was intentional) but also use it for later APIs
to the driver without it ever having known about it which was
_not_ intentional.
Check through the code and only use the monitor_sdata in the
relevant places (TX, MU-MIMO follow settings, TX power, and
interface iteration) when the WANT_MONITOR flag is set.

After the channel context emulation, there were reports that
changing the monitor channel no longer works. This is because
those drivers don't have WANT_MONITOR_VIF, so the setting the
channel always exits out quickly.
Fix this by always allocating the virtual monitor sdata, and
simply not telling the driver about it unless it wanted to.
This way, we have an interface/sdata to bind the chanctx to,
and the emulation can work correctly.

The code itself doesn't want to handle frames from the driver
if it's already stopped, but if the tasklet was queued before
and runs after the stop, then all bets are off. Flush queues
before actually stopping, RX should be off at this point since
all the interfaces are removed already, etc.

If we have a HW restart in the middle of a ROC period,
then there are two cases:
- if it's a software ROC, we really don't need to do
anything, since the ROC work will still be queued
and will run later, albeit with the interruption
due to the restart;
- if it's a hardware ROC, then it may have begun or
not, if it did begin already we can only remove it
and tell userspace about that.
In both cases, this fixes the warning that would appear
in ieee80211_start_next_roc() in this case.
In the case of some drivers such as iwlwifi, the part of
restarting is never going to happen since the driver will
cancel the ROC, but flushing the work to ensure nothing
is pending here will also result in no longer being able
to trigger the warning in this case.

At some point we thought perhaps this could be per link, but
really that didn't happen, and it's confusing. Radar detection
still uses the deflink to allocate the channel, but the work
need not be there. Move it back.

Instead of passing the full TPE elements, in all their glory
and mixed up data formats for HE backward compatibility, parse
them fully into the right values, and pass that to the drivers.
Also introduce proper validation already in mac80211, so that
drivers don't need to do it, and parse the EHT portions.
The code now passes the values in the right order according to
the channel used by an interface, which could also be a subset
of the data advertised by the AP, if we couldn't connect with
the full bandwidth (for whatever reason.)
Also add kunit tests for the more complicated bits of it.

If a link switch work was queued, and then a restart happened, the
worker might be executed before the reconfig, and obviously it will fail
(the HW might not respond to updates etc.)
So, don't perform the switch if we are in reconfig, instead - do it
at the end of the reconfig.

In case of restart, we currently reactivate multi-link on
interfaces before reconfiguring keys etc. which means the
drivers need to handle this case differently. Enable more
links later to allow them to handle it the same way.

Current mac80211 won't parsing puncturing bitmap when process EHT
Operation element in 6 GHz band or Bandwidth Indication element. This
leads to puncturing bitmap cannot be updated in related situations, such
as connecting to an EHT AP in 6 GHz band.
So supplement parsing of puncturing bitmap for these elements.

We sometimes need to check if a link is active, and this
is complicated by the fact that active_links has no bits
set when the vif isn't (acting as) an MLD. Add a small
new helper ieee80211_vif_link_active() to make that a bit
easier, and use it in a few places.

The building of elements is really mess, and really the only
reason we're not doing it in SKBs in the first place is that
the scan code in ieee80211_build_preq_ies() doesn't.
Convert ieee80211_build_preq_ies() to use an SKB internally
so that we can gradually convert other things to ..._put_*()
style interfaces.
