Subject: [dpdk-dev] [PATCH v5 2/4] net/ixgbe: add support of reset
Date: Fri, 30 Jun 2017 18:12:34 +0800	[thread overview]
Message-ID: <1498817556-64379-3-git-send-email-wei.dai@intel.com> (raw)
In-Reply-To: <1498817556-64379-1-git-send-email-wei.dai@intel.com>

Reset a NIC by calling dev_uninit and then dev_init.
Go through same way in NIC PCI remove without release of
ethdev resource and then NIC PCI probe function without
ethdev resource allocation.
