JumboFrames (9000 bytes or better) in "Ethernet" appeared back in the  
mid to late 1990's with the Alteon AceNIC right? (at least that is my  
first conscious memory of them) They are still outside the IEEE  
framework.  Frame sizes going extra-IEEE is one thing, I'm rather more  
skeptical of CRC's being able to go extra-IEEE.  Given there is  
perhaps a snowball's chance of the IEEE blessing JumboFrames, I  
suspect there is less than a snowball's chance of them blessing  
another CRC to address anything presented as "a jumboframe problem."   
So, to push a fix down to the link-layer is to effectively assert it  
is something that need never be fixed.
