 NFP ports belonging to same PF can be seen inside PMD initialization with a
-suffix added to the PCI ID: wwww:xx:yy.z_port_n. For example, a PF with PCI ID
+suffix added to the PCI ID: wwww:xx:yy.z_portn. For example, a PF with PCI ID
 0000:03:00.0 and four ports is seen by the PMD code as:

+Some dpdk applications can choose to use the MAC address to identify ports,
