Description

Currently ITM does not program a common flow table to contain the egress tunnel information. Due to this all applications need to be aware of the underlying tunnel port to program in their application pipeline. This feature aims to abstract out the underlying port information in a table that can be programmed by ITM, and applications can point to this table in their flows. The group will be created irrespective of the tunnel port being created, and applications need not act upon tunnel created/deleted events.
