 *       The framework can only be enabled with Linux. BSD is not supported.
 
-*       To detach a port, the port should be backed by a device that igb_uio
-        manages. VFIO is not supported.

 *       Not all PMDs support detaching feature.
-        To know whether a PMD can support detaching, search for the
-        "RTE_PCI_DRV_DETACHABLE" flag in PMD implementation. If the flag is
-        defined in the PMD, detaching is supported.
+        The underlying bus must support hot-unplug. If not supported,
+        the function ``rte_eth_dev_detach()`` will return negative ENOTSUP.
