+Subject: [PATCH 5/6] usb_gadget: set random rndis host MAC address to prevent
+ zero address
+
+This fixes zero host MAC:
+
+rndis0: MAC f6:45:91:9b:4e:43
+rndis0: HOST MAC 00:00:00:00:00:00
+
+and allows devive to automatically obtain IP addrest on PC host side
+zero MAC address prevented interface from autoconfiguring
