VDPA didn't work on a big-endian machine due to missing/incorrect
CPU<->LE data format conversions.

Add .set_vnet_le() function that always returns success, assuming that
vDPA h/w always implements LE data format. Otherwise, QEMU disables vDPA and
outputs the message:
"backend does not support LE vnet headers; falling back on userspace virtio"

Both svq->desc_next and "i" are in QEMU. We can skip the conversion
and assign directly.
Are you saying that desc_next[] should be in "CPU" and not LE form

Could you point me to those tests?

I’m observing a problem while testing VDPA with Nvidia ConnectX-6 (mlx5)
on s390.
Upon start, virtio_net_device_realize() tries to set a new MAC address
by VHOST_VDPA_SET_CONFIG which doesn’t do anything.
Later, the VM gets started and learns about the old address from
virtio_net_get_config(
