When converting an NS file, if the user is simply requesting a plain 1G
or 10G link, force BW shaping off, since the mere presence of property statements causes the CM to turn on linkdelays, which is typically not what users are after. Still a problem to deal with; the CM should throw an error if it gets this directive and there is non zero delay or loss. But what if the CM gets this directive with a BW that is *not* one of 1G or 10G? Should it through an error for this as well or assume the user knows that they are doing (yeah, right).
