Subject: [dpdk-dev] [PATCH v3 6/6] doc: update for two ports hairpin mode
Date: Thu,  8 Oct 2020 20:05:17 +0800
Message-ID: <1602158717-32038-7-git-send-email-bingz@nvidia.com> (raw)
In-Reply-To: <1602158717-32038-1-git-send-email-bingz@nvidia.com>

In the release notes, 2 ports hairpin mode feature is added.

In rte flow part, one suggestion is added to mention that metadata
could be used to connect the hairpin RX and TX flows if the hairpin
is working in explicit TX flow rule mode.

In the testpmd command line, the new parameter to set hairpin working
mode is described.
