+VF MAC address setting
+~~~~~~~~~~~~~~~~~~~~~~
+
+On ixgbe, the concept of "pool" can be used for different things depending on
+the mode. In VMDq mode, "pool" means a VMDq pool. In IOV mode, "pool" means a

+``rte_eth_dev_mac_addr_add()`` function can be used to add a VF's MAC address,
+as a workaround.
