None that have ever been accepted.  From a quick google for manufacturer  
support, 9216 looks like the most popular number.  But, as I said, it  
boils down to the largest frame *every* device on the LAN will accept.  If  
there is a single device that only supports "9000", then that's your  
limit.  And if there's a single non-JF device in the LAN, it throws a  
wrench into the whole thing. (This appears to be one of the sticking  
points as to why IEEE won't accept the addition of JF to any specs.)
