Hi,

If I understand correctly, this series adds support for 6 new features:

--- a/doc/guides/nics/features/hns3.ini
+++ b/doc/guides/nics/features/hns3.ini
@@ -8,6 +8,8 @@ Link status          = Y

None of those are available in 20.02, and LRO is not available in
20.05.

What happens if a user upgrades from 19.11.4 with any of these features
enabled to 20.02 or 20.05?
