If you succeed with openWRT, can you post your image for testing?

@frank-w im trying to compile dirver, but iāve got error
ERROR: modpost: "mtk_wcn_wmt_set_chipid" [/home/user/openwrt/build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_mt7623/mt6625l/connectivity/common/common_detect/mtk_wmt_detect.ko] undefined!
It seems to be some Makefile mistake. Maybe you know how to fix it?
i guess this error came because you try an incompatible/older version of the driver
you can get a working version for your kernelversion in my repo
Which kernelversion do you use and which version of driverā¦i remember i had this error in some 5.x kernel,but do not know how i have fixed it
@frank-w My kernel version is 5.10.134, and Iām using 5.11-main as you suggested. But I did not apply patches yet.
Could it be patch problem? And could I use newer version (e.g. from 5.12-main) with 5.10 linux kernel?
How do you use 2 kernelversions without applying patches 
You mean wifi driver from 5.11 with 5.10 base kernel?
Make sure you use only the first 3 patches from the driver (driver folder,include driver, changes outside driver dir), additional changing things for this newer version an may be not backwards compatibleā¦
Yes, exactly. Ok, iāll try to apply patches, may be it fix it.
And if it wonāt work, can I use wifi driver from your 5.12-main branch with 5.10 openwrt linux kernel version? Or its forbidden? =)
Itās not forbidden 
Ok,you use openwrtā¦ then it is maybe more complex as openwrt contains backports especially in network segment. That makes it hard for me to say āuse version xyā.
You could try using all versions above your base version till one works (except 6.0 which is currently broken) or use the 5.10 version (squashed into 3 patches in 5.11 branch) and apply patches one-by one i added in newer versions (fixing specific problems).
