A LLC2-speaking station can send only a predetermined number of frames before it must wait for an acknowledgment from
the receiver. Set this number to the maximum value that can be supported by the stations with which the router
communicates. Setting this value too large can cause frames to be lost, because the receiving station may not be able to
