The following provides sufficient information for the MAC entity to determin the size of the RI field and parse the frame properly. The detailed structure and contents for the RI field is described in ISO/IEC 10038:1993 and ISO/IEC 88022-2 : 1994 <- RI Field (Length represented by LTH Field) -> | | +------+--------+------------------------------+ | 3 | LTH | | | bits | 5 bits | | +------+--------+------------------------------+ RI = Routing Information (2 to 30 octets when present) LTH = Lenght (5 bits) (number of octets) > Yes, but you really need to tell the user when they attempt to configure > the interface with an invalid MTU as well.

And will when I get a chance to write it. :) /* Matthew N.
