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 C?dric Le Goater: https://www.mail-archive.com/kvm-ppc at 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
