Hi Long and Stephen, I see from the official documentation that the netvsc PMD does not support RSS RETA update https://doc.dpdk.org/guides-22.11/nics/overview.html. But the code has a callback hn_rss_hash_update registered for reta update. When the dpdk app invokes rte_eth_dev_rss_reta_update, it invokes hn_rss_hash_update . So is this a documentation discrepancy? If VF is removed and readded should the dpdk app take care of configuring the RSS RETA again?
