I'd suggest something like the following may be a bit clearer:
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
VF.
There is no RTE API to add a VF's MAC address from the PF. On ixgbe, the
``rte_eth_dev_mac_addr_add()`` function can be can be used to add a VF's MAC
address, as a workaround.
