/*
 TODO (roughly in that order)
 - Don't use structs to access the elements in the datastream.
 - Use tvb_..._item wherever possible
 - Add references to documentation (ETSI EN 300 175 parts 1-8)
 - Make things stateful
 - Once the capture format has stabilized, get rid of the Ethernet
 hack and use a proper capture type.
