From 160f0d11bbab08468fbddb0e5d3ee5bff63a9225 Mon Sep 17 00:00:00 2001 From: Li Zhang Date: Wed, 27 Oct 2021 12:13:58 +0300 Subject: [PATCH] doc: add metering limitation in mlx5 guide 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.
