drivers/net: release port upon close
Checks
Commit Message
From: Di ChenxuX <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().
This patch cover all the intel drivers

Just setting RTE_ETH_DEV_CLOSE_REMOVE in probe stage is not enough, you can see
the advice in http://git.dpdk.org/dpdk/commit/?id=23ea57a2a
"When enabling RTE_ETH_DEV_CLOSE_REMOVE, the PMD must free all its private resources for the port
in its dev_close function, it's advised to call the dev_close function in the remove function
in order to support removing a device without closing its ports".
You can refer to other PMD which has finished this transition, like
696202ca5396 ("net/mvpp2: remove resources when port is closed")
Also, I'd suggest to split it to several patches, one patch for one PMD.
Thanks,
Xiaolong
