Thank you very much for this information.
I just built an image with this driver, and it is working very well.
I used the latest available version on Github at this point, GitHub - EntropicEffect/rtl8822bu at 66aae0e630e9886acee2386c0623ca479130c8b8
Built with PROJECT=RPi ARCH=arm DEVICE=RPi2, didn't take too long, all good!
Please add the driver to the main release
