The cnmallocator package has a map of supported network drivers which are registered using a pkg-local driver registry. This registry is then used to load drivers, and if they have a 'local' DataScope, they aren't used for anything. Drivers with a 'global' DataScope are called to allocate cluster-wide network resources. Instantiating builtin network drivers may have unintended side-effects (e.g. the bridge driver registers a callback that should run when firewalld is reloaded), so libnetwork has dummy '*manager' drivers that do nothing but carry the same Capability than the original driver they masquerade. Put 'local drivers' (e.g. those with DataScope 'local') into a separate list that just contains drivers' name, and don't register them into the cnmallocator's driver registry. Remove all the dummy '*manager' drivers as they're not needed anymore. Signed-off-by: Albin Kerouanton <albinker@gmail.com>
