Subject: [dpdk-dev] [PATCH 2/4] net/ice: delete HW rings when releasing queues
Date: Fri, 17 Sep 2021 19:24:45 +0800	[thread overview]
Message-ID: <b8ed1ec48d876ff52a56665f3e6fbf067bf9ad7a.1631877273.git.wangyunjian@huawei.com> (raw)
In-Reply-To: <cover.1631877273.git.wangyunjian@huawei.com>

Normally when closing the device the queue memzone should be
freed. But the memzone will be not freed, when device setup
ops like:
 - rte_eth_bond_slave_remove
 - rte_eth_dev_internal_reset
 - eth_dev_rx_queue_config
 - dev_rx_queue_release
 - dev_close
 - dev_free_queues

In order to free the memzone, we can release the memzone
when releasing queues.
