Hi guys,

Sorry for the lack of response. I know people are waiting for
me, but these days I have too many things to do at the same time, and
it's difficult to find time.

In few words (I'll provide more detailed answers to the thread by
friday): I expected to post the mbuf rework patchset for this release,
which includes the structure changes (Jerin's patch for arm access,
timestamp, port, nb_segs, refcnt changes). But the patchset is clearly
not ready yet, it needs a rebase, and it lacks test.

Jerin, I know that you submitted your patch a long time ago, and I'm
the only one to blame, please do not see any vendor preference in it.

I'll check friday what's the effective state of the patchset in my
workspace. If I can extract a minimal patch that only change the
structure, I'll send it for discussion. But from what I remember, the
mbuf structure rework depends on changing the way we access the refcnt,
so it can be moved to the 2nd cache line.

If that's not possible, I'll try propose some alternatives.
