[dpdk-dev] [PATCH 10/11] net/hns3: fix Rx/Tx queue offload capability

[Wei Hu (Xavier)]

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

According to rte_eth_rx_queue_setup and rte_eth_tx_queue_setup API
function, rx_queue_offload_capa and rx_offload_capa, tx_queue_offload_capa
and tx_offload_capa must be mutually exclusive in the '.dev_infos_get' ops
implementation function. Otherwise, rte_eth_rx_queue_setup or
rte_eth_tx_queue_setup will fail, if user uses rx_offload_capa and
tx_offload_capa obtained by calling the rte_eth_dev_info_get API function.

Currently, offload capabilities are enabled for all Rx/Tx queues in hns3
PF and VF PMD driver, and offload capability only applied in a Rx/Tx
queue is not supported. This patch fixes Rx/Tx queue offload capability.

Fixes: 1f5ca0b460cd67 ("net/hns3: support some device operations")
Fixes: a5475d61fa34b8 ("net/hns3: support VF")
