This patch introduces the avtpsrc element which implements a typical network source. The avtpsrc element receives AVTPDUs encapsulated into Ethernet frames and push them downstream in the GStreamer pipeline. Implementation if pretty straightforward since the burden is implemented by GstPushSrc class. Likewise the avtpsink element, applications that utilize this element must have CAP_NET_RAW capability since it is required by Linux to open sockets from AF_PACKET domain.
