<snip> @Felipe: please _DO NOT_ take this series. After some more testing I discovered a bug. It is related to delaying registering a network interface until gadget's bind. Before the mentioned change a network interface was registered at the moment its corresponding usb function's directory was created, so it happened exactly once for each interface. After the change it is registered at function's bind and if a function happens to be used across several configurations, its network interface will be registered more than once which results in kernel BUG at net/core/dev.c:5143. I will post a corrected v3 series soon.
