No, but I do expect that you support code that is already there. There
was apparently zero testing done on the original patch and it caused
one very obvious regression. So how can we have any confidence
whatsoever that this patch doesn't break other things? Furthermore,
with all these claims of bugs I still don't see that _anyone_ has
taken the time to reproduce any issue and show that this patch
materially fixes any thing. I seriously don't understand how basic
testing could be such a challenge.

Anyway, what I expect is moot. It's up to davem to decide what to do
with this...

You being upset with a lack of testing is one issue, and is
legitimate.

But the fact that we can't support, and never could support, more than
one network header at a time except in a very special case for GRO
is very real.  And you must acknowledge that this was a very shaky
foundation upon which to erect the kinds of things you expect to work.
