I gotta say that the whole thing makes my head really hurt, and while
this conversation is about how to go about configuring things,
I've been unable to get a grip on how flows will actually behave with
these offloads present.

My overall starting point for thinking about this stuff was described
in this preso to broadcom a few years back:

More recently I did what I think is my funniest talk ever on these

Make some popcorn, take a look. :) I should probably have covered
ecn's (mis)behaviors at the end, but I didn't.

Steven hemminger's lca talk on these subjects was also a riot...

so somehow going from my understanding of how stuff gets configured,
to the actual result, is needed, for me to have any opinion at all.
have this stuff basically running already? Can you run various tests through it?
