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

[Li Zhang]

A meter policy with RSS/Queue action is not supported
when ``dv_xmeta_en`` enabled.

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.

Fixes: 51ec04d ("net/mlx5: connect meter policy to created flows")
