Subject: [dpdk-dev] [PATCH v2 1/2] ethdev: replace callback getting filter operations
Date: Fri, 12 Mar 2021 18:46:44 +0100
Message-ID: <20210312174645.162801-2-thomas@monjalon.net> (raw)
In-Reply-To: <20210312174645.162801-1-thomas@monjalon.net>

Since rte_flow is the only API for filtering operations,
the legacy driver interface filter_ctrl was too much complicated
for the simple task of getting the struct rte_flow_ops.

The filter type RTE_ETH_FILTER_GENERIC and
the filter operarion RTE_ETH_FILTER_GET are removed.
The new driver callback flow_ops_get replaces filter_ctrl.
