MCS data uses the format described in IEEE P802.11be/D2.0, May 2022,
9.4.2.313.4, convert it into the format expected by the firmware.

When ath12k used as station mode, it entered here as well as AP mode.

But remote is AP device for station mode, then remote AP device do not 
have the only_20mhz data(EHT-MCS Map (20 MHz-Only Non-AP STA)).

Also 20 MHz should be same for 5 GHz/6 GHz(MODE_11BE_EHT20) and 2.4 
GHz(MODE_11BE_EHT20_2G), right?

What issue are you seeing? Please elaborate.

The default case will be entered for both AP and non-AP STA modes for 
all bandwidths.

If the device is a 20-MHz-only device, it will skip 320, 160 and 
directly enter the default case where 'if' condition will be true.

If the device is not a 20-MHZ-only device then it will enter the 'else' 
condition after processing 320 and 160 as applicable.

Good point, I will add a check for MODE_11BE_EHT20_2G as well here.

When I configured AP with 11BE-EHT mode for 20 MHz bandwidth on 5 GHz/6 
GHz band,
and then connect to the AP with ath12k for station mode. Then the 
peer_phymode
is MODE_11BE_EHT20, and then ath12k entered the default in function
ath12k_peer_assoc_h_eht() and use the bw_20 which is assigned with
eht_cap->eht_mcs_nss_supp.only_20mhz.

For station mode of ath12k, the eht_cap->eht_mcs_nss_supp is from the IE 
"Supported
EHT-MCS and NSS Set" in assoc resp of AP in function 
ieee80211_eht_cap_ie_to_sta_eht_cap().
Now it is "EHT-MCS Map (BW <= 80MHz): 0x222222" for the AP(11BE-EHT mode 
for 20 MHz
bandwidth on 6 GHz band) in my test as below IEs.

The field only_20mhz and field _80 are union in struct 
ieee80211_eht_mcs_nss_supp, the
value of field _80 is 0x222222 for this AP, then the value of field 
only_20mhz is like this:
rx_tx_mcs7_max_nss=0x22,
rx_tx_mcs9_max_nss=0x22,
rx_tx_mcs11_max_nss=0x22,
rx_tx_mcs13_max_nss=0.

Then ath12k_mac_set_eht_mcs() will get value 0 fro mcs13 because it used 
the field only_20mhz
passed by ath12k_peer_assoc_h_eht().

Understood, I fixed the default case to check for the he_cap field for 
the bandwidth support instead of peer_phymode in v5.
