Subject: [PATCH 4/4] net: mvneta: clean txdesc before usage
Date: Thu, 15 Sep 2016 12:38:17 +0200 [thread overview]
Message-ID: <1473935897-9252-5-git-send-email-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <1473935897-9252-1-git-send-email-u.kleine-koenig@pengutronix.de>
This fixes tx error detection which triggered way too often because the
hardware doesn't seem to clear the error bits on success
