I’m working with a proprietary Ethernet traffic generator/analyzer and Ethereal consistently reports a shorter length (by 4 bytes) and doesn’t display the FCS.  Is there an option that I’m missing or something?  I know the fcs is present and that the frame is 4 bytes longer than reported because I’ve used two different analyzers to verify this.  I’ve included a pdf printout of one of the packets as seen in Agilent’s Advisor, I’ve also included a capture of the packet in question.  Any help with this will be greatly appreciated.
