Subject: [dpdk-stable] [dpdk-dev] [PATCH 2/3] event/octeontx2: fix sub event type violation
Date: Mon, 29 Jun 2020 07:03:27 +0530
Message-ID: <20200629013329.5297-2-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20200629013329.5297-1-pbhagavatula@marvell.com>

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

In OCTEONTX2 event device we use sub_event_type to store the ethernet
port identifier when we receive work from OCTEONTX2 ethernet device.
This violates the event device spec as sub_event_type should be 0 in
the initial receive stage.
Set sub_event_type to 0 after copying the port id.

Fixes: 0fe4accd8ec8 ("event/octeontx2: add Rx adapter fastpath ops")
Cc: stable@dpdk.org
