The ack-filter has rules about which bits and options changing need to be preserved to avoid losing information from the ack stream, and therefore prevent two acks from being coalesced.

The version of Cake in the SCE tree adds the former NS bit (which SCE uses as ESCE) to that list.  SCE still works fine without that patch, it just preserves more information on the reverse path and thus makes the behaviour a bit smoother.
