Subject: [dpdk-dev] [PATCH 1/5] net/e1000: release port upon close
Date: Mon, 2 Sep 2019 10:27:41 +0000 [thread overview]
Message-ID: <20190902102745.66695-2-chenxux.di@intel.com> (raw)
In-Reply-To: <20190902102745.66695-1-chenxux.di@intel.com>
Set RTE_ETH_DEV_CLOSE_REMOVE upon probe so all the private resources
for the port can be freed by rte_eth_dev_close().
Signed-off-by: Di ChenxuX <chenxux.di@intel.com>
