Why buffer the packet until the lookup succeeds? Why not
just accept the first few packets while a lookup is done
in parallel then, if subsequent packets appear to be
coming from an incorrect ITR, just start dropping? That
way we can defeat *sustained* DOS attacks, which are
the only ones we really care about anyway.
