Subject: [PATCH net-next v3 6/9] net/mlx5e: TC, add hw counter to branching actions
Currently a hw count action is appended to the last action of the action
list. However, a branching action may terminate the action list before
reaching the last action.
Append a count action to a branching action.
In the next patches, filters with branching actions will read this counter
when reporting stats per action.
