ath12k wrong MCS rate in monitor-mode

[Frank Lindner]

Hi,

I am using ath12k devices, QCN9274 from Compex.
In monitor-mode, all captured data-frames are saved with MCS3. 
A parallel capture of ath10k device shows MCS7 or 15. 
The captured data is a wifi4 or wifi5 traffic. 

Is there a fix available or is this firmware?
