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. - Jonathan Morton=
