Hi Mark, It's clear that we're thinking from two very different starting points. You want to make a few very small changes to the current way of using jumboframes, all the while accepting all the current limitations that make that virtually nobody uses them. What I want to do is remove th

Hi all: Sorry to drop in whitout anything that important to say: jumbograms are not the same as jumboframes - the first is IPv6 (and carries a max of 4GB data), the later is Ethernet (and it carries up to 9KB data). So if we want to keep the discussion fine tuned, we might want not to mix up
