[dpdk-dev] [PATCH v1] drivers/net: release port upon close

chenxux.di at intel.com chenxux.di at intel.com
Tue Aug 27 03:01:22 CEST 2019


From: Di ChenxuX <chenxux.di at 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().
This patch cover all the intel drivers
