Mark and David, can you pull the 3.13-td-changes-reverted branch again, and see if the latest patch fixes your issue? It disables scatter gather for the ax88179_178a device, but only when it's operating at USB 3.0 speeds. Please test with it plugged into a USB 3.0 port, and when it's plugged in behind a USB 2.0 hub.
