[Thomas Monjalon]

26/10/2021 12:10, 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 dv_xmeta_en enabled.

Thank you for the explanation.

Did you understand my comment about the formatting?
You must add quotes like that: ``dv_xmeta_en``
Look at other occurences in the doc.
