Name	Type	Description
UnstructuredIo	simple module	Attaches an application to the cellular NIC of a UE whose session is of type Unstructured (the UE's sessionType parameter, see LteUe): the payload goes down to the NIC and comes up from it as is, with no transport or network layer in between. Packets arriving on trafficIn are sent to the NIC tagged with the "unstructured" protocol; what the NIC delivers up as that protocol leaves on trafficOut. The module registers as the node's receiver of the protocol, so a UE has at most one of it. It is connected to the UE's network-layer dispatcher (see the unstructuredApp submodules of LteUe).
