Subject: [PATCH  net-next v3 6/9] net/mlx5e: TC, add hw counter to branching actions
Date: Mon, 6 Feb 2023 15:54:39 +0200	[thread overview]
Message-ID: <20230206135442.15671-7-ozsh@nvidia.com> (raw)
In-Reply-To: <20230206135442.15671-1-ozsh@nvidia.com>

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.
