I think you will need to go back to 4.19 based driver, or add a hack to #ifdef that code out while compiling
in openwrt.

I did a brief test with the 4.19 ct driver and it seems to work OK in my test setup.  Since it appears openwrt
will be stuck on 4.19 for a while, I'll put some more effort into keeping my 4.19 tree up to date.

Also, I found a nasty bug with mgt frames in htt-mgt mode yesterday, and uploaded new beta firmware to my
web page...will post csums and such to this list later today.

Thanks,
Ben
