Subject: [dpdk-dev] [PATCH v4 1/8] lib/librte_ether: support device reset
Date: Tue, 7 Jun 2016 14:53:03 +0800 [thread overview]
Message-ID: <1465282390-6025-2-git-send-email-zhe.tao@intel.com> (raw)
In-Reply-To: <1465282390-6025-1-git-send-email-zhe.tao@intel.com>
Add an API to reset the device.
It's for VF device in this scenario, kernel PF + DPDK VF.
When the PF port down/up, APP should call this API to
reset VF port. Most likely, APP should call it in its
management thread and guarantee the thread safe.
