this is a how-to include rtl8821cu into kernel tree for future compilation
1 Extract the compressed file into drivers/net/wireless/rockchip_wlan/
2 Modify drivers/net/wireless/rockchip_wlan/Kconfig and change about line 47

rtl8821cu.tar.xz

This way, rtl8821cu can be loaded as a module with modprobe and insmod
 
I hope this can help somebody
 

We will test
