[dpdk-stable] [PATCH v5] doc: document a limitation for a meter with RSS action

[Thomas Monjalon]

The title should mention "mlx5 guide" as the scope.

26/10/2021 13:53, Li Zhang:
> A meter policy with RSS/Queue action is not supported
> when ``dv_xmeta_en`` enabled.

The quotes are RST syntax.
Raslan, while merging, you can remove the quotes from the commit log.

> 
> When ``dv_xmeta_en`` enabled in legacy creating flow,
> it will split into two flows
> (one set_tag with jump flow and one RSS/queue action flow).
> For meter policy as termination table,
> it cannot split flow and
> cannot support when ``dv_xmeta_en`` enabled.
