Regarding RSS RETA update in netvsc PMD

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?
Regards,
Nandini

Yes, looks like a doc is missing.
