 The function name to use when creating the function directory is "ncm".
 The NCM function provides these attributes in its function directory:
 
-	=============== ==================================================
-	ifname		network device interface name associated with this
-			function instance
-	qmult		queue length multiplier for high and super speed
-	host_addr	MAC address of host's end of this
-			Ethernet over USB link
-	dev_addr	MAC address of device's end of this
-			Ethernet over USB link

 and after creating the functions/ncm.<instance name> they contain default
 values: qmult is 5, dev_addr and host_addr are randomly selected.
