The MTU for a 16mb ring will be higher than the MTU for a 4mb ring. Actually 'can be higher' is a better way to put it. Some cards have a fixed speed (config the speed with a DOS util and live with it. Some cards will autodetect ring speed on insert. Some cards only support 4mb. > Also should we be going with TOKENxxx or ISO88025 ???? ISO88025 as that is what the sys/net/if_types.h calles it. /* Matthew N.
