usbnet: ipheth: prevent OoB reads of NDP16 In "NCM mode", the iOS device encapsulates RX (phone->computer) traffic in NCM Transfer Blocks (similarly to CDC NCM). However, unlike reverse tethering (handled by the `cdc_ncm` driver), regular tethering is not compliant with the CDC NCM spec, as the device is missing the necessary descriptors, and TX (computer->phone) traffic is not encapsulated at all. Thus `ipheth` implements a very limited subset of the spec with the sole purpose of parsing RX URBs.
Splendid. Perfect. Regards Oliver
