I was hoping for something a bit more than that. Can you please go check
with the people who made the hardware and those who wrote the manual
(probably not the same ones) what is actually up and down, and then
report on what they said.

It's fairly obvious that allocating 192 bytes instead of 128 should
never hurt (unless we run out of muram), but it would be nice with an
official "Yes, table 8-111 is wrong, it should say 192", or
alternatively, "No, table 8-53 is wrong, those MTU etc. fields don't
really exist". Extra points for providing details such as "first
revision of the IP had $foo, but that was never shipped in real
products, then $bar was changed", etc.

Thanks,
Rasmus
