Subject: [PATCH 09/10] net: fsl-fman: Sync rx buffers for device initially
Date: Wed, 8 May 2019 11:03:06 +0200 [thread overview]
Message-ID: <20190508090307.17729-10-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190508090307.17729-1-s.hauer@pengutronix.de>
The rx buffers must be given to the device initially to work properly.
Otherwise the first packets are corrupted.
