Hi,

I am trying to maximize the bandwidth of WCN7850. Does anyone know the
performance status of WCN7850 in mainline? It's about 160Mbps in 6GHz
band and ~600Mbps in 5GHz band on sm8650 platform in my test. The
firmware is from below links:
https://github.com/kvalo/ath11k-firmware/raw/master/ath12k-testing/WCN7850/hw2.0/board.bin
https://github.com/kvalo/ath11k-firmware/raw/master/ath12k-testing/WCN7850/hw2.0/regdb.bin

While it is ~940Mbps in both 5GHz and 6GHz band with
Android/linux6.1.25, . But the firmware names are different per log,
amss20.bin on Android. Not sure whether the driver is totally
different for Android/linux6.1.25 and mainline.

Do you have any idea that the low performance on mainline is due to
driver difference or TX/RX power configuration, or firmware version?

Thanks for your input!
