f502065559 wifi: mt76: move struct ieee80211_chanctx_conf up to struct mt76_vif
Move struct ieee80211_chanctx_conf up to struct mt76_vif to allow the
connac2 library can access the struct ieee80211_chanctx_conf * member in
struct mt76_vif.

1f39e1d95a wifi: mt76: Drop unnecessary error check for debugfs_create_dir()
debugfs_create_dir() returns ERR_PTR and never return NULL.

As Russell suggested, this patch removes the error checking for
debugfs_create_dir(). This is because the DebugFS kernel API is developed
in a way that the caller can safely ignore the errors that occur during
the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in
start_creating() which can handle it gracefully. So these checks are
unnecessary.

413f05d68d wifi: mt76: get rid of false alamrs of tx emission issues
When the set_chan_info command is set with CH_SWITCH_NORMAL reason,
even if the action is UNI_CHANNEL_RX_PATH, it'll still generate some
unexpected tones, which might confuse DFS CAC tests that there are some
tone leakages. To get rid of these kinds of false alarms, always bypass
DPD calibration when IEEE80211_CONF_IDLE is set.

The compiler actually complains on 'mt7915_get_et_strings()',
'mt792x_get_et_strings()' and 'mt7996_get_et_strings()' due to the same
reason: fortification logic inteprets call to 'memcpy()' as an attempt
to copy the whole array from its first member and so issues an overread
warning. These warnings may be silenced by passing an address of the whole
array and not the first member to 'memcpy()'.

debd133ab2 wifi: mt76: use atomic iface iteration for pre-TBTT work
In addition to the previous series I posted, over time I'd
also like to get rid of the iflist_mtx in mac80211. That
isn't easy now since lots of places use iteration and would
have to be audited, but even a cursory look suggests that
mt76 might be more problematic than most since holding the
wiphy lock for the latency-sensitive pre-TBTT work could be
an issue.

Convert the pre-TBTT work to use atomic iteration and then
sending the device commands outside of it.

3176205933 wifi: mt76: mt7603: improve stuck beacon handling
Before preparing the new beacon, check the queue status, flush out all
previous beacons and buffered multicast packets, then (if necessary)
try to recover more gracefully from a stuck beacon condition by making a
less invasive attempt at getting the MAC un-stuck.

baa19b2e4b wifi: mt76: mt7603: rework/fix rx pse hang check
It turns out that the code in mt7603_rx_pse_busy() does not detect actual
hardware hangs, it only checks for busy conditions in PSE.
A reset should only be performed if these conditions are true and if there
is no rx activity as well.
Reset the counter whenever a rx interrupt occurs. In order to also deal with
a fully loaded CPU that leaves interrupts disabled with continuous NAPI
polling, also check for pending rx interrupts in the function itself.

8e73c0455b wifi: rtw89: declare MCC in interface combination
MCC (multi-channel concurrency) supports two combinations as below.
* P2P-GO + STA
* P2P-GC + STA
We add the corresponding ieee80211_iface_limit for it into
ieee80211_iface_combination.

Besides, for multiple channels, it must run with mac80211 chanctx.
So, only with it, ieee80211_iface_combination can allow MCC case.

5f499ce69b wifi: rtw89: pause/proceed MCC for ROC and HW scan
During (TDMA-based) MCC (multi-channel concurrency), the below two
cases might not have a good behavior on channel usage.
* ROC (remain on channel)
* HW scan
So, we tend to separate them from MCC.

The two cases would expect to operate the channel to which they want.
However, during MCC, channels are scheduled by FW MCC state mechanism.
So, channels cannot be controlled explicitly. To avoid the two cases
from operating wrong channels with chance, we pause MCC (essentially
stop FW MCC) once the two cases are coming. And then, we proceed MCC
again (essentially restart FW MCC) once the two cases finish.

a4d7c872eb wifi: rtw89: mcc: fix NoA start time when GO is auxiliary
Under TDMA-based MCC (multi-channel concurrency), there are two roles,
reference and auxiliary. We arrange MCC timeline based on time domain
of reference role. Then, we calculate NoA start time according to MCC
timeline.

Besides, when MCC runs GO+STA mode, we plan an offset between GO time
domain and STA time domain to make their TBTTs have a time gap.

However, if GO is auxiliary role instead of reference role, NoA start
time is described by STA time domain instead of GO time domain. To fix
this, we apply the offset mentioned above to NoA start time to convert
time domain from STA to GO.
