[dpdk-dev] [PATCH 1/6] net/hns3: modify max reset fail retry count

[Min Hu (Connor)]

From: HongBo Zheng <zhenghongbo3@huawei.com>

When the device is very busy, VF reset may have to be
retried many times to succeed, leading to the current
max reset fail retry count not enough.

This patch modify max reset fail retry count to 30 to
enhance the reliability of reset function.

[dpdk-dev] [PATCH 2/6] net/hns3: fix delay time for waiting to stop rxtx

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

When the primary process executes dev_stop or is being reset, the packet
sending and receiving functions is changed. In this moment, the primary
process requests secondary processes to change their Rx/Tx functions, and
delays a period of time in case of crashes when queues are still in use.
The delay time depends on the number of queues actually used, instead of
the maximum number of queues supported by the device.

[dpdk-dev] [PATCH 3/6] net/hns3: fix incorrect fake queue rollback

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

When the device supports independent Rx/Tx queues, fake queues do not need
to be created in unequal Rx/Tx queues case. However, dev_configure fails
to be executed on the device supported independent Rx/Tx queues, the
current rollback code logic contains the fake queue. As a result, the fake
queue is created. When dev_configure is successfully called again, these
fake queues still exists and are configured to the hardware.

[dpdk-dev] [PATCH 5/6] net/hns3: fix config max queues to zero when fails

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

The "cfg_max_queues" maintains configured max queue numbers from user,
and is equal to the maximum of "nb_rx_queues" and "nb_tx_queues" in
"dev->data".

From the ethdev layer framework, "nb_rx/tx_queues" in "dev->data" were set
to zero in rte_eth_dev_configure() if ops.dev_configure in PMD fails to be
executed, In addition, if ops.dev_configure in HNS3 PMD failed, the fake
queues are also cleared on a device that does not support independent Rx/Tx
queues.

Therefore, the "cfg_max_queues" should be also set to zero when
dev_configure fails.
