Hi Larry,

In the dslw packet there is a field that is calll largest frame size (L)

Largest Frame Size---Carries the largest frame size bits across the DLSw
connection. This field is implemented to ensure that the two
end-stations always negotiate a frame size to be used on a circuit that
does not require DLSw partners to resegment frames.

Regards

Robert
