Subject: [dpdk-dev] [PATCH 2/7] ethdev: add support of restoration of queue state
Date: Sat, 27 May 2017 16:22:04 +0800	[thread overview]
Message-ID: <1495873329-43303-3-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1495873329-43303-1-git-send-email-wei.dai@intel.com>

As dev->dev_ops->dev_start may change dev->data->rx_queue_state[]
and dev->data->tx_queue_state[], this patch adds rxq_restore_state[]
and txq_restore_state[ ] for restoration.
In the restoration process, PMD should start or stop each Rx or Tx
queue according to dev->data->rx_restore_state[] or
dev->data->tx_restore_state[].
