[dpdk-dev] [PATCH] net/dpaa2: set queues after reconfiguration

From: Akhil Goyal <akhil.goyal at nxp.com>

if dpaa2_dev_tx_queue_setup is called multiple times, the
assignment of device->data->tx_queues is not done, as a result
tx_queues remain NULL after reconfiguration.
This patch sets the tx_queues from the device private data to the
usable device tx queues.

Fixes: 7ae777d064e8 ("net/dpaa2: add support for congestion notification")
