[PULL 1/1] vdpa: Allow vDPA to work on big-endian machine

[Jason Wang]

From: Konstantin Shkolnyy <kshk@linux.ibm.com>

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"
