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
these two concepts.
BTW, I'm all in favour in rethinking the "jumbo" issue (or as someone once put
it, to give an end to tinygrams), and of course, to makeit as much Autoconf as
possible.
If we make some simple arithmetics, we can see the size of the switching effort
we're posing on networks equipments with this 1500B tinygrams.
Cheers,

If you're going to require admins enabling jumbograms on their network,
it's never going to happen. People are just going to avoid enabling it
because when you do everything breaks. As it stands today the general
consensus is "disable jumbograms, coz even if you manage to get it all
working today, something will change tomorrow and you'll have a nasty
problem to fix".
If a simple solution can be found to having one link support multiple
MTU's then thats where I think we should be heading :) If one can't be
found, then we should investigate what we can do to make this as easy as
possible for end users.
