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

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.
