+Application Programming Interface
+---------------------------------
+
+In DPDK release v16.11 an API for ixgbe specific functions has been added to the ixgbe PMD.
+The declarations for the API functions are in the header ``rte_pmd_ixgbe.h``.
 
 Sample Application Notes
-~~~~~~~~~~~~~~~~~~~~~~~~
+------------------------
 
 testpmd
-^^^^^^^
+~~~~~~~
 
 By default, using CONFIG_RTE_IXGBE_RX_OLFLAGS_ENABLE=y:
 
 .. code-block:: console
 
-    ./x86_64-native-linuxapp-gcc/app/testpmd -c 300 -n 4 -- -i --burst=32 --rxfreet=32 --mbcache=250 --txpt=32 --rxht=8 --rxwt=0 --txfreet=32 --txrst=32 --txqflags=0xf01

 When CONFIG_RTE_IXGBE_RX_OLFLAGS_ENABLE=n, better performance can be achieved:
 
 .. code-block:: console
 
-    ./x86_64-native-linuxapp-gcc/app/testpmd -c 300 -n 4 -- -i --burst=32 --rxfreet=32 --mbcache=250 --txpt=32 --rxht=8 --rxwt=0 --txfreet=32 --txrst=32 --txqflags=0xf01 --disable-hw-vlan

 l3fwd
-^^^^^
+~~~~~
 
 When running l3fwd with vPMD, there is one thing to note.
 In the configuration, ensure that port_conf.rxmode.hw_ip_checksum=0.
 Otherwise, by default, RX vPMD is disabled.
 
 load_balancer
-^^^^^^^^^^^^^
+~~~~~~~~~~~~~
 
 As in the case of l3fwd, set configure port_conf.rxmode.hw_ip_checksum=0 to enable vPMD.
 In addition, for improved performance, use -bsz "(32,32),(64,64),(32,32)" in load_balancer to avoid using the default burst size of 144.

+MTU setting
+~~~~~~~~~~~
+
+Although the user can set the MTU separately on PF and VF ports, the ixgbe NIC
+only supports one global MTU per physical port.
+So when the user sets different MTUs on PF and VF ports in one physical port,
+the real MTU for all these PF and VF ports is the largest value set.
+This behavior is based on the kernel driver behavior.
