By default there is no rtnetlink event generated when registering a
netdev with rtnl_link_ops until its rtnl_link_state is switched to
initialized (RTNL_LINK_INITIALIZED). This causes issues with user
tools like NetworkManager which relies on such event to manage links.
Fix that by setting link to initialized (via rtnl_configure_link).
