@@ -116,10 +116,18 @@ Currently the Link Bonding PMD library supports following
modes of operation:
#. Calls to ``rte_eth_tx_burst`` must have a buffer size of at least 2xN,
where N is the number of slaves. This is a space required for LACP
frames. Additionally LACP packets are included in the statistics, but
they are not returned to the application.
+ This mode also supports enabling dedicated rx and tx queues for handling
+ LACP frames separately from fast application path, resulting in
+ a potential performance improvement.

+.. note::
+ Currently mlx5 doesn't work with enabled dedicated queues due to
+ an issue with RTE flow rule creation prior to port start.
