* Improve support for Mellanox ConnectX-4 cards (100/50/25GbE)
** Only CentOs/RedHat 7.2 and up is supported due to OFED issues
** Improve 64Byte Stateleess performance
-* Cisco VIC is fully supported now
+* Cisco VIC is fully supported
* Stateless neighboring protocols infra and first protocols support/Python API - TBD point to documentation and examples
* Stateful - ARP support for Client clustering mode (a.k.a APIC-EM) see here link:trex_manual.html#_client_clustering_configuration[Client Clustering]
* Added Stateless performance trend document link:trex_analytics.html[trex performance trend]

+[IMPORTANT]
+=====================================
+Change of behavior - trex config file (/trex/cfg.yaml) should include a distinct MAC address or distinct IP address.
+Not setting the port information :
+ before v2.12 : src MAC addr == 00:00:00:01:00:00
+ v2.12 and up : src MAC addr == HW MAC address
