2f72c759fd wifi: iwlwifi: dbg-tlv: avoid extra allocation/copy 
In iwl_dbg_tlv_alloc_trigger() the code makes a copy just
to modify it and pass it to another function to make a copy
again. Change the API to return the copy so the adjustment
can be done without another copy.

10159a4566 wifi: iwlwifi: disable eSR when BT is active 
eSR should be disabled when BT Coex is active and:

- LB link is the secondary link and the predicted BT penalty

0bc7d1d4e6 wifi: rtw89: pci: validate RX tag for RXQ and RPQ 
PCI RX ring is a kind of read/write index ring, and DMA and ring index are
asynchronous, so suddenly driver gets newer index ahead before DMA. To
resolve this rare situation, we use a RX tag as helpers to make sure DMA
is done.

The RX tag is a 13-bit value, and range is from 1 ~ 0x1FFF, but 0 isn't
used so should be skipped.

Only enable this validation to coming WiFi 7 chips, because existing
chips use different design and don't really meet this situation.

Add missed rx_ring_eq_is_full for 8851BE by the way.

This *mostly* reverts commit 1e1b11b6a1 ("nl80211/cfg80211: Specify
band specific min RSSI thresholds with sched scan").

During the review of a new patch [1] it was observed that the
functionality being modified was not actually being used by any
in-tree driver. Further research determined that the functionality was
originally introduced to support a new Android interface, but that
interface was subsequently abandoned. Since the functionality has
apparently never been used, remove it. However, to mantain the
sanctity of the UABI, keep the nl80211.h assignments, but clearly mark
them as obsolete.

fdccafad7e wifi: iwlwifi: add support for a wiphy_work rx handler 
The wiphy_work infra ensures that the entire worker will run
with the wiphy mutex. It is useful to have RX handlers
running as a wiphy_work, when we don't want the handler to
run in parallel with mac80211 work (to avoid races).

For example - BT notification can disable eSR starting from the next
patch.
In ieee80211_set_active_links we first check that eSR is
allowed, (drv_can_activate_links) and then activate it.
If the BT notif was received after drv_can_activate_links
(which returned true), and before the activation - eSR will be
activated when it shouldn't.
If BT notif is handled with the wiphy mutex, it can't run in
parallel to ieee80211_set_active_links, which also holds that
mutex.

Add the necessary infrastructure here, for use in the next commit.

Without SMP the function is just a stub that returns an error code. Add
a compile time check for CONFIG_SMP in the interest of not logging an
error if setting affinity is not possible anyway.

de0c2cdcb7 wifi: iwlwifi: mvm: limit EHT 320 MHz MCS for STEP URM 
If the STEP (the interface between MAC and PHY) is in URM
(a lower speed mode) then we cannot use 320 MHz MCS > 9.
Therefore, limit the MCS in our capabilities in this case.
Note that this also limits the TX/rate scaling since that
takes both TX and RX capabilities into account.

1. Most APs have a beacoon interval of 100ms.
2. Sending and receiving probe require some delay.
3. Setting channel to HW also requires some delays
