Subject: [dpdk-dev] [PATCH 1/2] ethdev: allow negative values in flow rule types
Date: Thu, 25 Jun 2020 19:03:47 +0300
Message-ID: <20200625160348.26220-2-getelson@mellanox.com> (raw)
In-Reply-To: <20200625160348.26220-1-getelson@mellanox.com>

RTE flow items & actions use positive values in item & action type.
Negative values are reserved for PMD private types. PMD
items & actions usually are not exposed to application and are not
used to create RTE flows.

The patch allows applications with access to PMD flow
items & actions ability to integrate RTE and PMD items & actions
and use them to create flow rule.
