[dpdk-dev] [PATCH 1/2] examples/ethtool: fix Rx/Tx queue setup with rte socket id

[Min Hu (Connor)]

From: Chengwen Feng <fengchengwen@huawei.com>

The ethtool use the socket_id which get from rte_eth_dev_socket_id API
in the init stage, but use the rte_socket_id API to get socket_id when
setting ringparam.

This patch make sure it call rte_eth_dev_socket_id API to get
socket_id when setting ringparam.

The explanation is missing something.
Please tell why it is wrong.

Hi, Thomas,
It is advised that bind queue resources to the NUMA node where the
device resides, not the NUMA node corresponding to the thread where the
command line resides. And that will be better.

I know, but in the commit message, you give function name
without saying that rte_socket_id is the running socket
while rte_eth_dev_socket_id is the device socket.

Please make your commit messages more obvious for anyone reading.
Story telling is usually a good approach.

[dpdk-dev] [PATCH 2/2] examples/ethtool: add closing port operation

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

Currently, ethtool directly ends the process after 'quit' cmd. In this
case, software resources are not released and hardware resources of the
device are not uninstalled.

This patch adds closing port operation to release resources.

It would be better to add EAL cleanup in the main function.

So why adding it in this patch about ethdev close?

From: Chengwen Feng <fengchengwen@huawei.com>

In DPDK, 'rte_socket_id' means the running socket while
'rte_eth_dev_socket_id' is the device socket. For better performance,
memory which queue setup used and device should be in the same socket.

This patch make sure it calls rte_eth_dev_socket_id API to get device
socket_id when setting ringparam.
