[Qemu-devel] [PATCH v3 0/3] virtio-net/vhost-net: share cross-endian enablement

[Greg Kurz]

Since QEMU 2.4.0, vhost-net uses the cross-endian support of TAP devices to
fix vnet headers. In fact, virtio-net can do the same instead of hackily
patching headers in virtio_net_hdr_swap().

This series moves the enablement of cross-endian support from vhost-net to
virtio-net: both vhost and full emulation can now benefit from it. Of course
we keep the current hack to fall back on when the backend doesn't support
cross-endian.

      virtio-net: use the backend cross-endian capabilities
      Revert "vhost-net: tell tap backend about the vnet endianness"
      virtio: drop the virtio_needs_swap() helper
