From: Li Zhang Date: Wed, 27 Oct 2021 09:13:58 +0000 (+0300) Subject: doc: add metering limitation in mlx5 guide X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=160f0d11bbab08468fbddb0e5d3ee5bff63a9225;p=dpdk.git 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.
