In some cases with Generic FLow, it is only required to show the pattern of spec and mask, but no need to add the flow. Therefore, add an option in packetforge so that users can show spec and mask only. Type: improvement Signed-off-by: Ting Xu <ting.xu@intel.com> Change-Id: I7b3040689eb82d0b58924712ee6fc9cfa0a42fa1
