  * OPacket - A frame on the wire
  *======================================================================================*/
 
 /** @brief A class representing a data frame on the wire.
  *
  * The whole family of the packet classes are used when capturing frames from a network.
  * Most standard network protocols in use share a common architecture, which mostly is
  * a packet header and then the packet payload. In layered architectures, each lower layer
  * encapsulates data from its upper layer - that is it
  * treats the data from its upper layer as payload and prepends an own header to the packet,
  * which - again - is treated as the payload for the layer below. The figure below is an
  * example for how such a data frame is composed out of packets, e.g. when sending a mail.
  *
  * <pre>
  *                                                       | User Data |     == Mail Data
  *                                         | SMTP Header | User Data |     == SMTP
  *                           | TCP Header  | SMTP Header | User Data |     == TCP
  *               | IP Header | TCP Header  | SMTP Header | User Data |     == IP
  *  | MAC Header | IP Header | TCP Header  | SMTP Header | User Data |     == MAC
  *
  * </pre>
  *
  * The example is trimmed for simplicity, because the MAC (Medium Access Control) layer
  * also contains a few more levels of encapsulation.
  * Since the type of the payload is more or less independent from the encapsulating protocol,
  * the header must be inspected before attempting to decode the payload. Hence, the
  * encapsulation level varies and can't be deduced without actually looking into the packets.
  *
  * For actually working with captured frames, it's useful to identify the packets via names and
  * insert them into a parent/child - relationship based on the encapsulation. This is why
  * all packet classes derive from QObject. The amount of overhead caused by the QObject is
  * not a problem in this case, because we're talking about a theoratical maximum of about
  * 10 packets per captured frame. We need to stuff them into a searchable list anyway and the
  * QObject also cares about destroying the sub-, (child-) packets.
  *
  * This enables us to perform a simple look for packets of a certain type:
  * @code
  * OPacketCapturer* pcap = new OPacketCapturer();
  * pcap->open( "eth0" );
  * OPacket* p = pcap->next();
  * OIPPacket* ip = (OIPPacket*) p->child( "IP" ); // returns 0, if no such child exists
  * odebug << "got ip packet from " << ip->fromIPAddress().toString() << " to " << ip->toIPAddress().toString() << oendl;
  *
