usbnet: ignore endpoints with invalid wMaxPacketSize [ Upstream commit 8d3d7c2029c1b360f1a6b0a2fca470b57eb575c0 ] Endpoints with zero wMaxPacketSize are not usable for transferring data. Ignore such endpoints when looking for valid in, out and status pipes, to make the drivers more robust against invalid and meaningless descriptors. The wMaxPacketSize of these endpoints are used for memory allocations and as divisors in many usbnet minidrivers. Avoiding zero is therefore critical.
