This is RX packet injection, not TX. So the injection goes up - from the driver to mac80211. Since we use it to test some mvm data path stuff, we don't want to inject at mac80211 level. > But reading from the code makes me suspect that this isn't really normal > packet injection, more like passing full descriptors to the hw. Did I > understand correctly? For injecting at driver level we need the injected packet to contain a fake of the HW descriptor for the driver processing. This descriptor isn't being passed to the hw, but to the driver since it is RX. The code isn't creating the descriptor, but it is validating length and other checks to make sure we won't access invalid memory or so.
