Improved Linux Driver for Railnk USB WiFi Cards RT8070 RT3070 RT3370 RT3572 RT5370 RT5372 RT5572 Based on original Ralink Driver v2.6.1.3 (10/22/2012)

Features:

• fixed statistics for recieved packets and bytes count reported by the driver (cat /proc/net/dev)
• compiles on modern Linux kernels. Tested with the version 5.0
  
• LED on Ralink 3070. In original driver if you compile without LED support (HAS_LED_CONTROL_SUPPORT in os/linux/config.mk) than your LED stays turned on all the time the WiFi card switched on. In this driver the LED will be switched off after you up the interface.
  

Reverse engineered undocumented features:

• change MAC through configuration file RT2870STA.dat (MacAddress=12:34:45:67:ad:be as first parameter)
• turn off annoying debug messages in kernel log (set debug level, run "iwpriv ra0 set Debug=0", possible levels 0~5)
• WirelessMode=11 (11n-only with 5G band). Was not present in iwpriv_usage.txt
