Subject: [PATCH] net/iavf: add VF reset check
Date: Thu, 25 May 2023 10:17:37 +0800 [thread overview]
Message-ID: <20230525021737.1921818-1-zhichaox.zeng@intel.com> (raw)
This commit adds a VF reset check before the dev_reset, so that
the application can check if the iavf device comes out of reset
when calling the rte_eth_dev_reset.
