Subject: [dpdk-dev] [PATCH 8/8] net/hns3: remove unused assignment for RSS key
Date: Thu, 14 Jan 2021 21:33:37 +0800 [thread overview]
Message-ID: <1610631217-14216-9-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1610631217-14216-1-git-send-email-oulijun@huawei.com>
The default RSS key does not need to be configured repeatedly
when call hns3_dev_configure function with the NULL RSS key
because the default RSS key has been configured when the PMD
driver run hns3_do_start function with starting device.
Besides, it will not overwrite the inited key if rte_eth_dev_configure
API will be called directly and RSS key is NULL after init PMD
driver.
Therefore, the assignment for RSS key in hns3_dev_configure
function is unncessary.
