Outch, that does cause a big problem for store-and-forward switching. 
You basically can't split up packets from a single stream without very 
careful cut-through switching, which we obviously can't do in Linux. 
That seems a rather silly requirement given that higher level protocols 
already deal with packet reordering.  Why not an option to say stuff the 
standard?
