@@ -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.
