-            In P4Runtime, action profiles (i.e. group tables) are specific to one or more tables.
-            Mapping of treatments depends on the target table. How do we derive the target table from here?
-
-            Solution:
-            - Change GroupDescription to allow applications to specify a table where this group will be called from.
-
-            Hack:
-            Assume we support pipelines with only one action profile associated to only one table, i.e. derive the
