A. Feature

The following steps demonstrate Realtek Wireless Adapter Linux RF HW/SW Tx Tool. 
The HW Tx Mode only support the new VHT chipset,like as 8814A, 8822B, 8821B, .....
It had depend on with  linux wlan driver version,must be over the v4.3.24_r15693. 
This is a simple User guide,
The rtwpriv V3 version is Integrate HW/SW Tx tool.
We use Linux utility “rtwpriv” to I/O control config WLAN driver,

B. Software Package
	1. Readme.txt
	2. Rtw_Config.txt
	3. rtwpriv.cpp/rtwpriv.h
	4. rtwpriv
	
C. Build the realtek RF Hw Tx tool.
	Q. How to build rtwpriv tool?
    A.[Linux]
        Just "make", and you will get executable file "rtwpriv".
			If you want to use another OS platform, please to modify the Makefile of toolchain.
		
D. Use Example:
1. insert the wlan.ko driver.
#insmod wlan.ko

2. enable wlan interface
#ifconfig wlan0 up

3. Enter wlan MP mode
#rtwpriv wlan0 mp_start

3. execute the rtwpriv tool to launch RF HW Tx.
 rtwpriv wlan0 [Channel] [Bandwidth] [ANT_PAH] [RateID] [TxMode] [Packet Interval] [PacketLength] [Packet Count] [Packet Pattern]
#rtwpriv wlan0 36 0 a HTMCS0 1   	//Start Tx
#rtwpriv wlan0 stop		       //Stop Tx	

4. To adjust the Tx power index , 
   if you want to adjust [CONTINUOUS Tx] power, please frist to stop Tx,then do adjust power index.
#rtwpriv wlan0 mp_txpower patha=30,pathb=30,pathc=30,pathd=30
