That was clear from the first mail. Maybe it got clear from my mail, 
that I wanted to know what are the downsides of our behaviour.

I failed to read from the specs that we are wrong seeing MTU as unique 
(i.e. per interface, not per protocol).

Also, lwIP will always have limitations compared to bigger stacks to be 
more lightweight. The question is if this MTU thing is something we must 
change or we can live with. Noone has yet brought a good reason for a 
change.
