Subject: [dpdk-stable] [PATCH 2/2] app/testpmd: fix tunnel offload private items location
Date: Mon, 19 Apr 2021 16:02:04 +0300
Message-ID: <20210419130204.24348-2-getelson@nvidia.com> (raw)
In-Reply-To: <20210419130204.24348-1-getelson@nvidia.com>

Flow rules used in tunnel offload model require application to query
PMD for private flow elements and explicitly add these elements to
flow rule.
Tunnel offload model does not restrict private elements location in
a flow rule.
The patch places tunnel offload private PMD flow elements between
general RTE flow elements in a rule.

Fixes: 1b9f274623b8 ("app/testpmd: add commands for tunnel offload")
