The largest frame size (including DLC header and info field
but not any MAC-level or framing octets) this DLSw can forward
on any path through itself. This object can represent any box-
level frame size forwarding restriction (e.g., from the use
of fixed-size buffers). Some DLSw implementations will have
no such restriction.
This value will affect the LF size of circuits during circuit
creation. The LF size of an existing circuit can be found in
can be found in the RIF (Routing Information Field).
