Hardware does not support individually enable/disable/reset the Tx or Rx
queue in hns3 network engine, driver must enable/disable/reset Tx and Rx
queues at the same time.
Currently, hns3 PMD driver does not support the scenarios as below:
1) When calling the following function, the input parameter nb_rx_q and
nb_tx_q are not equal.
rte_eth_dev_configure(uint16_t port_id, uint16_t nb_rx_q,
uint16_t nb_tx_q,
const struct rte_eth_conf *dev_conf);
2) When calling the following functions to setup queues, the
cumulatively setup Rx queues are not the same as the setup Tx queues.
rte_eth_rx_queue_setup(uint16_t port_id, uint16_t rx_queue_id,,,);
rte_eth_tx_queue_setup(uint16_t port_id, uint16_t tx_queue_id,,,);
However, these are common usage scenarios in some applications, such as,
l3fwd, ip_ressmbly and OVS-DPDK, etc.
This patch adds support for this usage of these functions by setup fake
Tx or Rx queues to adjust numbers of Tx/Rx queues. But these fake queues
are imperceptible, and can not be used by upper applications.
