Subject: [dpdk-dev] [PATCH 1/1] ethdev: rename a flow shared action error code
Date: Fri, 20 Nov 2020 10:54:38 +0100
Message-ID: <20201120095438.2620653-1-thomas@monjalon.net> (raw)

In the experimental function rte_flow_shared_action_destroy()
introduced in DPDK 20.11, the errno ETOOMANYREFS was used.
This errno is not always available on Windows,
so it is preferred using EBUSY instead.
