      When added the secondary interface support we noticed we need to iterate multiple time to be able to register per netns to netlink to learn about interface notification, while we forgot to free all unsuccessful handler to avoid leaking FD, also TCX hook unlike TC it needs to be explicity removed when interface goes down
