Subject: [dpdk-dev] [PATCH v2 61/62] net/sfc: support encap. flow items in transfer rules
Date: Tue, 20 Oct 2020 10:13:41 +0100
Message-ID: <1603185222-14831-62-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1603185222-14831-1-git-send-email-arybchenko@solarflare.com>

From: Ivan Malov <ivan.malov@oktetlabs.ru>

Add support for flow items VXLAN, Geneve and NVGRE to
MAE-specific RTE flow implementation.

Having support for these items implies the ability to insert
so-called outer MAE rules and refer to them in MAE action rules.
The patch takes care of all necessary facilities to do that.
