Mukesh was going to post an RFC this week but that has to be
delayed.

Going to be delayed further. Might as well move it out out of Xen 4.3
feature list to Xen 4.4.

I think we came up with so many design things that Roger is going to
be burried with this for a year or so :-(

But I would say that the 'multi-page' aspect of this (which I think
is actually the indirect descriptor) is going to show up in v3.10.
Which is two months away. The only Xen patches are to update the
protocol description.

I think we are waiting for Matthew. He posted the Linux ones but
they need to be updated. Could make it for v3.10.

Not for 4.3. Might not even be ready for v3.10.

Not sure, Daniel?
