[dpdk-dev] [PATCH] net/hns3: support getting Tx and Rx queue information

[dpdk-dev] [PATCH] net/hns3: support getting Tx and Rx queue information

[Wei Hu (Xavier)]

From: Huisong Li <lihuisong@huawei.com>

This patch adds support for querying Rx/Tx queue information.

Currently, if there are not available Rx buffer descriptors in recieving
direction based on hns3 network engine, incoming packets will always be
dropped by hardware. This patch reports the '.rx_drop_en' information to
DPDK framework in the '.dev_infos_get', '.rxq_info_get' and
'.rx_queue_setup' ops implementation function.

Can you please separate this into two patches, first one for 'rx_drop_en'
related changes to existing code, second one to add queue info get functions?

And you may prefer to request backporting the 'rx_drop_en' patch.

'rxq' should not be 'NULL' at this stage, because of the "queue_id >=
dev->data->nb_rx_queues" check in 'rte_eth_rx_queue_info_get()'.
Can you please check if it can be 'NULL' and if it can be, better to check it in
the ethdev API, instead of doing in each PMD, both for 'rxq' & 'txq'.

Thanks for you suggestion.

I will update them in V3.

OK, I will send a email to add check rxq & txq in the 
rte_eth_rx_queue_info_get

and rte_eth_tx_queue_info_get API function.

Thanks, Xavier.

[dpdk-dev] [PATCH v3 0/3] minor updates for getting queue info

[Wei Hu (Xavier)]

This series include 3 patches.
One patch is a minor update to add checking whether the related Tx or Rx
queue has been setuped in the rte_eth_rx_queue_info_get and
rte_eth_tx_queue_info_get API function to avoid illegal address access.

And the other two patches for hns3 PMD driver.

[dpdk-dev] [PATCH v3 1/3] net/hns3: report Rx drop packets enable configuration

[Wei Hu (Xavier)]

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

Currently, if there are not available Rx buffer descriptors in recieving
direction based on hns3 network engine, incoming packets will always be
dropped by hardware. This patch reports the '.rx_drop_en' information to
DPDK framework in the '.dev_infos_get', '.rxq_info_get' and

This series include 3 patches.
One patch is a minor update to add checking whether the related Tx or Rx
queue has been setuped in the rte_eth_rx_queue_info_get and
rte_eth_tx_queue_info_get API function to avoid illegal address access.

And the other two patches for hns3 PMD driver.

[dpdk-dev] [PATCH v4 1/3] net/hns3: report Rx drop packets enable configuration

[Wei Hu (Xavier)]

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

Currently, if there are not available Rx buffer descriptors in receiving
direction based on hns3 network engine, incoming packets will always be
dropped by hardware. This patch reports the '.rx_drop_en' information to
DPDK framework in the '.dev_infos_get', '.rxq_info_get' and
'.rx_queue_setup' ops implementation function.
