Subject: [dpdk-dev] [PATCH v3 1/4] ethdev: add support of NIC reset
Date: Thu, 29 Jun 2017 16:34:01 +0800	[thread overview]
Message-ID: <20170629083404.1271-2-wei.dai@intel.com> (raw)
In-Reply-To: <20170629083404.1271-1-wei.dai@intel.com>

A DPDK application can reset a NIC and keep its port id afterwards.
It means that all SW resources allocated in ethdev layer should be
kept and  SW and HW resources of the NIC in PMD need to be reset
in similar way that it runs PCI dev_uninit() and then dev_init().
The sequence of dev_uninit() and dev_init() can be packed into a
single interface API rte_eth_dev_reset().
