+Subject: [PATCH] app/testpmd: add ethernet peer command
+
+This command will simulate the process of setting the
+eth-peer from command line.
+
+It will be useful to perform extra testing.
+
+usage:
+ testpmd> set eth-peer <port_id> <peer_addr>.
+
+Signed-off-by: Wisam Jaddo <wisamm@mellanox.com>
+Acked-by: Wenzhuo Lu <wenzhuo.lu@intel.com>
+
+This will help Debian/Ubuntu to have the MLX PMDs much more testable
+while at the same time not affecting
+ a) any other formerly existing PMDs
+ b) any other parts than the testpmd helper
+ c) not changing things if not specified
