I have just completed the switch to use a single qemu tree for each of the
versions we support (qemu-xen AKA upstream and qemu-xen-traditional AKA our
historical fork).
Instead of the individual Xen release specific repositories the QEMU trees
are now:

This patch adds all the necessary infrastructure to allow a frontend to
specify toeplitz hashing of network packets on its receive side. (See
netif.h for details of the xenbus protocol).
The toeplitz hash algorithm itself was based on pseudo-code provided by
Microsoft at:
https://msdn.microsoft.c
This series adds xen-netback support for hash negotiation with a frontend
driver, and an implementation of toeplitz hashing as the initial negotiable
algorithm.
Patch #1 re-imports the canonical netif header from Xen, which contains
the necessary definitions and a type required by subsequent patch
