d43701c587 wifi: iwlwifi: mvm: change iwl_mvm_flush_sta() API 
[ Upstream commit 3917629697 ]

This API is type unsafe and needs an extra parameter to know
what kind of station was passed, so it has two, but really it
only needs two values. Just pass the values instead of doing
this type-unsafe dance, which will also make it better to use
for multi-link.

64c277f632 wifi: iwlwifi: mvm: Don't always bind/link the P2P Device interface 
[ Upstream commit 84ef7cbe90 ]

It is not necessary to keep the P2P Device bound/linked to a PHY
context when there is no active ROC.

Modify the P2P Device flows so the binding/linking would be done
only while ROC is active. With this change the switch_phy_ctxt()
is no longer needed so remove it.

12a89f0177 wifi: iwlwifi: remove 'use_tfh' config to fix crash 
This is equivalent to 'gen2', and it was always confusing to have
two identical config entries. The split config patch actually had
been originally developed after removing 'use_tfh" and didn't add
the use_tfh in the new configs as they'd later been copied to the
new files. Thus the easiest way to fix the init crash here now is
to just remove use_tfh (which is erroneously unset in most of the
configs now) and use 'gen2' in the code instead.

There's possibly still an unwind error in iwl_txq_gen2_init() as
it crashes if TXQ 0 fails to initialize, but we can deal with it
later since the original failure is due to the use_tfh confusion.

Instead of relying on the AP STA ID and dereferencing our
firmware -> mac80211 STA array when we really only need
the STA, not the per-link information (and might not have
it, e.g. for a pairwise key installation where this is
relevant), keep track of the AP STA as a pointer to the
mac80211 STA, protected by the mutex. Then use it here in
the key code instead.

Johannes Berg says:

====================
Major stack changes:

 * TC offload support for drivers below mac80211
 * reduced neighbor report (RNR) handling for AP mode
 * mac80211 mesh fast-xmit and fast-rx support
 * support for another mesh A-MSDU format
   (seems nobody got the spec right)

Major driver changes:

Kalle moved the drivers that were just plain C files
in drivers/net/wireless/ to legacy/ and virtual/ dirs.

hwsim
 * multi-BSSID support
 * some FTM support

ath11k
 * MU-MIMO parameters support
 * ack signal support for management packets

rtl8xxxu
 * support for RTL8710BU aka RTL8188GU chips

rtw89
 * support for various newer firmware APIs

ath10k
 * enabled threaded NAPI on WCN3990

iwlwifi
 * lots of work for multi-link/EHT (wifi7)
 * hardware timestamping support for some devices/firwmares
 * TX beacon protection on newer hardware

b8a85a1d42 wifi: iwlwifi: mvm: rxmq: report link ID to mac80211 
Add a fw_id_to_link_sta array in mvm to track the link
STA for each firmware station ID, and then use that to
report the link a frame was received on (since we know
the station ID from firmware).

Notably, this fixes beacon tracking for the correct link
since mac80211 now queues and processes those on the one
link identified by the link ID only.

The firmware now allows adding a link that's not yet bound
to a PHY context. Make use of that to align the driver with
mac80211's API expectations. For now, just add the link at
