+* **Unsuitable IOVA mode may be picked as the default**
+
+ Not all kernel drivers and not all devices support all IOVA modes. EAL will
+ attempt to pick a reasonable default based on a number of factors, but
+ there may be cases where the default may be unsuitable.
+
+ It is recommended to use the `--iova-mode` command-line parameter if the
+ default is not suitable.
