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()'.

It turns out that the code in mt7603_rx_pse_busy() does not detect actual

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.

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.

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.

though we should use for_each_sband_iftype_data() or similar. Fortunately
there's ieee80211_get_he_iftype_cap_vif() which is just what we need here so
use it to get HE capabilities.

WCN7850 and QCN9274 currently use the same structure rx_msdu_end_qcn9274
for msdu_end. But content of msdu_end on WCN7850 is different from that of
QCN9274. Need to update it for WCN7850, otherwise will get the wrong

For example, TID is no longer in WCN7850's msdu_end. But
ath12k_dp_rx_process_err() and ath12k_dp_rx_process_wbm_err() still get
TID from msdu_end. So an uncertain value will be used in these two
functions on WCN7850.
Therefore, add new structure rx_msdu_end_wcn7850 for WCN7850.
