Heh.  With the first iteration of the bismark project I'm trying to get to
where I have less than 30ms latency under load and have far larger problems
to worry about than jumbo frames. I'll be lucky to manage 1/10th that
(300ms) at this point.

Not, incidentally that I mind the idea of jumbo frames. It seems silly to be
saddled with default frame sizes that made sense in the 70s, and in an age
where we will be seeing ever more packet encapsulation, reducing the header
size as a ratio to data size strikes me as a very worthy goal.
