RTL8812AU/21AU and RTL8814AU drivers

Specifically adapted for the sm8150 Android kernel.

Important!

* Use "ip" and "iw" instead of "ifconfig" and "iwconfig"
     It's described further down, READ THE README!

* v5.3.4 is the stable branch, not this, but this does have
  better range then branches below + more fixes from Realtek

Make

Building the driver for the OnePlus 7 Pro, using clang:

export ARCH=arm64
export SUBARCH=arm64
export KSRC="/path/to/kernel/source"
export KBUILD_OUTPUT="/path/to/kernel/build/output"
export CROSS_COMPILE="/path/to/gcc_toolchain"
export CC_DIR="/path/to/clang/bin"
make -j$(nproc --all)

Loading the driver on the phone (root required!)

Execute the following commands on the phone:

su
insmod 8814au.ko

Using the driver as main wifi interface

Make sure the module has been loaded, but your usb wifi adapter is NOT connected. Then follow this closely:

Disable wifi in android
Remove internal wifi interfaces:

su
iw dev wlan0 del
iw dev wlan1 del

Connect your USB wifi adapter
Enable wifi in android. The usb wifi adapter will now be used.

Notes

Root is required for every command!

For setting monitor mode:

Set interface down

ip link set wlan0 down

Set monitor mode

iw dev wlan0 set type monitor

Set interface up

ip link set wlan0 up

For setting TX power:

$ sudo iw wlan0 set txpower fixed 3000

LED control

statically by module parameter in /etc/modprobe.d/8812au.conf or wherever, for example:

options 88XXau rtw_led_ctrl=0

value can be 0 or 1

or dynamically by writing to /proc/net/rtl8812au/$(your interface name)/led_ctrl, for example:

$ echo "0" > /proc/net/rtl8812au/$(your interface name)/led_ctrl

value can be 0 or 1

check current value:

$ cat /proc/net/rtl8812au/$(your interface name)/led_ctrl

USB Mode Switch

0: doesn't switch, 1: switch from usb2.0 to usb 3.0 2: switch from usb3.0 to usb 2.0

$ rmmod 88XXau
$ modprobe 88XXau rtw_switch_usb_mode:int (0: no switch 1: switch from usb2 to usb3 2: switch from usb3 to usb2)
