1500 MTU made sense when network was 10 megabit/s.
Now that we have gig and 10GE (and soon general availability of 100GE), I
don't understand why 9000 makes people excited, if we're going to do a
serious effort towards larger MTU, let's make it 150000 then (100x) or at
least 64k.
6x size different isn't that much, and it's going to involve a lot of work
to make it happen, so if we're going to do that work, do it properly.
