+13. RNDIS function
+==================
+
+The function is provided by usb_f_rndis.ko module.
+
+Function-specific configfs interface
+------------------------------------
+
+The function name to use when creating the function directory is "rndis".
+The RNDIS 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/rndis.<instance name> they contain default
+values: qmult is 5, dev_addr and host_addr are randomly selected.
+Except for ifname they can be written to until the function is linked to a
+configuration. The ifname is read-only and contains the name of the interface
+which was assigned by the net core, e. g. usb0.
+
+By default there can be only 1 RNDIS interface in the system.
+
+Testing the RNDIS function
+--------------------------
+
+Configure IP addresses of the device and the host. Then:
+
+On the device: ping <host's IP>
+On the host: ping <device's IP>
