+VF MAC address setting
+~~~~~~~~~~~~~~~~~~~~~~
+
+On ixgbe, the concept pool can be used for different things. It depends on the
+mode. In VMDq mode, the pool means a VMDq pool. In IOV mode, the pool means a
+VF.
+When setting the parameters of a pool, in VMDq mode, it's for a VMDq pool, in
+IOV mode, it's for a VF.
+There's no RTE API to add a VF's MAC address from PF. On ixgbe, there's a
+workaround to do it. "rte_eth_dev_mac_addr_add" also can be used to add a VF's
+MAC address.
