This patch series implements multiple transmit and receive queues (i.e.
multiple shared rings) for the xen virtual network interfaces.

quoted

The series is split up as follows:
  - Patch 1 brings the 'grant_copy_op' array back into struct xenvif, in
    preparation for multi-queue support. See the patch itself for more details.
- Patches 2 and 4 factor out the queue-specific data for netback and
   netfront respectively, and modify the rest of the code to use these
   as appropriate.
- Patches 3 and 5 introduce new XenStore keys to negotiate and use
   multiple shared rings and event channels, and code to connect these
   as appropriate.
- Patch 6 documents the XenStore keys required for the new feature
   in include/xen/interface/io/netif.h

All other transmit and receive processing remains unchanged, i.e. there
is a kthread per queue and a NAPI context per queue.

Would it be possible to also put these somewhere in a tree (or branch of the
xen-tree), so it is more easy to pull and test ?

I cannot speak for Andrew. FWIW you can save this thread and use 'git
am' to apply them to 'net-next'.

Wei.

I don't currently have a public-facing git repo for this. If you'd 
prefer I can send you the patches directly in a tarball, which you may 
be able to apply more easily than grabbing them from email threads?
