This makes it possible to create a set of LEDs for Mellanox systems:
"msx6710", "msx6720", "msb7700", "msn2700", "msx1410", "msn2410",
"msb7800", "msn2740", "msn2100".
Driver obtains led devices according to system configuration, provided
through system DMI data, like fan1:green, fan1:red and creates devices in
form: "devicename:colour:function".
led setting is controlled through on board CPLD Lattice device.
For setting particular led off, solid,
blink (blink requires ledtrig-timer module):
echo 0 > /sys/class/leds/status\:green/brightness
echo 1 > /sys/class/leds/status\:green/brightness
echo timer > /sys/class/leds/status\:green/trigger
