Pretty much everything in ipv6 will be over the MTU...  on ipv4 we  
disabled this because when you talk to things that don't speak TCP you  
have a packet over the MTU you try TCP it times out in 30 seconds then  
you send it anyway via UDP.  So why have a 30 seconds timeout when you  
don't need too.
