Yea. BE support is around for legacy stuff. So I'm not sure it's all
that important to support that mode in NFV/DPDK applications.
If it becomes important, for virtio 0.9 you won't be able to
support transparently in dpdk anyway - you'll need a new
vhost-user message to get the endian-ness of the guest,
and do byteswaps conditionally, adding overhead.
Maybe going virtio 1 only is the sane thing to do for these
applications.
