This option allows vhost to support guests with a different byte

ordering from host while using legacy virtio.
|

|
Userspace programs can control the feature using the
|
|
VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
|
|
|
|
This is only useful on a few platforms (ppc64 and arm64). Since it
|
|
adds some overhead, it is disabled by default.

If unsure, say "N".
