Subject: [PATCH 0/3] vhost_net: support for cross endian guests

Hi,

This patchset allows vhost_net to be used with legacy virtio
when guest and host have a different endianness. It is based
on previous work by Cédric Le Goater:

https://www.mail-archive.com/kvm-ppc@vger.kernel.org/msg09848.html

As suggested by MST:
- the API now asks for a specific format (big endian) instead of the hint
  whether byteswap is needed or not (patch 1)
- rebased on top of the virtio-1 accessors (patch 2)

Patch 3 is a separate fix: I think it is also valid for virtio-1.

Please comment.
