Subject: [dpdk-dev] [PATCH v5 01/15] eventdev: remove software Rx timestamp
Date: Fri, 30 Oct 2020 18:29:26 +0100
Message-ID: <20201030172940.1073558-2-thomas@monjalon.net> (raw)
In-Reply-To: <20201030172940.1073558-1-thomas@monjalon.net>

This a revert of the commit 569758758dcd ("eventdev: add Rx timestamp").
If the Rx timestamp is not configured on the ethdev port,
there is no reason to set one.
Also the accuracy  of the timestamp was bad because set at a late stage.
Anyway there is no trace of the usage of this timestamp.
