This flag is annoying because it puts a lot of logic into mac80211
that could just as well be in the driver (only iwlmvm uses it) and
the implementation is also broken for MLO.
Remove the flag in favour of calling drv_mgd_prepare_tx() without
any conditions even for the deauth-while-assoc case. The drivers
that implement it can take the appropriate actions, which for the
only user of DEAUTH_NEED_MGD_TX_PREP (iwlmvm) is a bit more tricky
than the implementation in mac80211 is anyway, and all others have
no need and can just exit if info->was_assoc is set.

When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR
Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.
Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.
Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.

BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it
in mvmvif:disable_esr_reason requires extracting the BT Coex bit before
checking if EMLSR is blocked or not for a specific vif.
Therefore, change the BT Coex bit to be an exit reason and not a
blocker. On link selection, EMLSR mode will be re-calculated for the 2.4
GHz link instead of checking that bit.
While at it, move the relevant function declarations to the EMLSR
functions area in mvm.h

mac80211 invokes the driver callback drv_can_activate_links() from
ieee80211_set_active_links to verify it can activate the desired link
combination.
However, ieee80211_set_active_links is called with more than one link in
2 cases:
- After driver's link selection decided to enter EMLSR
- From debugfs, for testing purposes.
For both cases there is no need to recompute all the considerations
determining whether to activate EMLSR.
Instead, only check if the vif is not blocked for EMLSR.

There are reasons for which we need to exit EMLSR, but not to block it
completely, and there are reasons for which we need to block EMLSR.
For both reason types we have the enum iwl_mvm_esr_state, when the
blocking reasons are stored in the `mvmvif::esr_disable_reason` bitmap.
This change introduces the APIs to use in the different cases:
- iwl_mvm_exit_esr - will exit from EMLSR mode.
- iwl_mvm_block_esr - will update the bitmap and exit EMLSR, to
be used for the blocking reasons only.
- iwl_mvm_unblock_esr - will update the bitmap. To be used for the
blocking reasons only.

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.

Currently the driver exits eSR by calling
iwl_mvm_esr_mode_inactive() before updating the FW
(by deactivating one of the links), and therefore before
sending the EML frame notifying that we are no longer in eSR.
This is wrong for several reasons:
1. The driver sends SMPS activation frames when we are still in eSR
and SMPS should be disabled when in eSR
2. The driver restores RLC configuration as it was before eSR
entering, and RLC command shouldn't be sent in eSR
Fix this by calling iwl_mvm_esr_mode_inactive() after FW update

eSR should be disabled when BT Coex is active and:
- LB link is the primary link.
- LB link is the secondary link and the predicted BT penalty
(the wifi loss rate caused by BT interference) is higher
than a given threshold.
If one of the conditions above is no longer true then re-enable eSR.
In order to implement this, add support for version 5 of
BT_PROFILE_NOTIFICATION, in which the bt penalty is provided
by FW.

eSR is activated when a chanctx is assigned to more than one link.
During eSR activation we should disable RLC for both phys, and configure
the FW with a special phy command for both phys.
Currently we assign the phy_ctxt to the link only after eSR activation,
so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW.
Fix this by first assigning the new phy_ctxt to the link and then
doing the eSR activation.

When the vif is in MLD mode, we'll get a vif links change from
non-zero to zero on disassociation, which removes all links in
the firmware and adds the 'deflink' the driver/mac80211 has.
This causes the firmware to clear some internal state.
However, in non-MLD mode, this doesn't happen, and causes some
state to be left around in firmware, which can particularly
cause trouble with the ref-BSSID in multi-BSSID, leading to an
assert later if immediately making a new multi-BSSID connection
with a different ref-BSSID.
Fix this by removing/re-adding the link in the non-MLD case
when the channel is removed from the vif. This way, all of the
state will get cleared out, even if we need the deflink, which
is more for software architecture purposes than otherwise.

As session protection API is moving to be per link instead of per mac,
move the time events to be per link too.
Since there is only one concurrent time event per mac, it feels
unnecessary to have the time_event as a member of iwl_mvm_link_info.
(That way we will have to iterate over all links each time we want to
clear a time event, and also we will need mac80211 to tell us the link
id when mgd_tx_complete() is called.)
So leave this as a member of iwl_mvm_vif, but add the link id to the
time_event structure.
The link id in time_event will only be maintained and used for:
1. When SESSION_PROTECTION_CMD is supported (before it, we don't have MLO)
2. For time_events of types SESSION_PROTECT_CONF_ASSOC,
SESSION_PROTECT_CONF_P2P_DEVICE_DISCOV, and
SESSION_PROTECT_CONF_P2P_GO_NEGOTIATION
(not for aux roc/ Hot Spot time_events).
For P2P, non-MLO connections, and pre-MLD API, deflink id, meaning 0,
will be used

Add simple logic that would allow using EMLSR in case
there are multiple valid links:
- In case the connection establishment has just been
completed try to find a valid link pair for EMLSR
functionality where one of the links in the pair is
the current active link.
- In case the valid links changed after connection
was already established, try to find a valid link pair
for EMLSR functionality, in case the EMSLR is not active
yet.
If a valid link pair is found call mac80211 to asynchronously
set the new link pair, otherwise continue using the current active
links.

Add a per-link debugfs entry in iwlmvm level so we can read/write link
related parameters.
Do it by implementing the link_add_debugfs API introduced by mac80211.
Each entry will have a path like this:
.../netdev:wlan0/link-X/iwlmvm/<file_name>
for each link X.
For non-MLD vifs this callback is called when the original vif
debugfs dir is also created, so handle that case by not creating
the 'iwlmvm' directory again.
Note that we don't have to worry about the cleaning the iwlmvm/*
directory as it is already done by mac80211 when removing the link
(or netdev).
