Install rtl8812au on ubuntu

做太多次了，每次update kernel就做一次，決定自己把他寫起來...

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/abperiasamy/rtl8812AU_8812AU_linux.git

cd rtl8812AU_8812AU_linux
sudo make
sudo make install
sudo modprobe 8812au

done
