1. 11b TX test
	wlan_mfg_tx_bg(ch, WLM_RATE_11M, txpwr)
	- ch: channel number
	- txpwr: -1 means default power or value in mili dBm (15000 for 15dBm)
	
2. 11g TX test
	wlan_mfg_tx_bg(ch, WLM_RATE_54M, txpwr)
	- ch: channel number
	- txpwr: -1 means default power or value in mili dBm (15000 for 15dBm)
	
3. 11n TX test
	wlan_mfg_tx_n(ch, WLM_MCS_RATE_7, txpwr)
	- ch: channel number
	txpwr: -1 means default power or value in mili dBm (15000 for 15dBm)
	
4. RX test
	wlan_mfg_rx(ch)
	- ch: channel number
	
5. Get received packets
	wlan_mfg_rx_getpkt(&count)
	- count: received packet count
	
6. Non-modulation TX test
	wlan_mfg_carrier_tone(ch)
	- ch; channel number

7. Stop MFG test
	wlan_mfg_stop()
