	Protocol     : WORD;
  end;
  (** Ethernet - Packet **)
  PEthernetPckt = ^TEthernetPckt;
  TEthernetPckt = Packed record
    Header : TEthernetHdr;
    Data   : Array[0..0] of uchar;
  End;

  (** IP - Header **)
  PIPHdr  = ^TIPhdr;
  TIPHdr   = packed record
    EthernetHeader : TEthernetHdr;
    Verlen         : UCHAR;
    Service        : UCHAR;
    Length         : WORD;
