Nope, "-s" in editcap is like "-s" in tcpdump and dumpcap and TShark  
and Wireshark; it specifies the maximum number of bytes in a packet,  
and anything past that is cut off, so "-s 8"  cuts off everything  
*except* for the first 8 bytes of a packet.

We have no tool to cut off the first 8 bytes of a packet.  What is it  
that the original poster really needs here?
