AccessPointDriver used to declare get_services, manage_service,
get_available_updates, apply_updates, get_packages, install_package and
remove_package as NotImplementedError stubs. Those stubs preceded
OpenWrtSystemMixin and OpenWrtPackageMixin in the MRO and shadowed their working
implementations, so this driver carried a forwarder for each one purely to
delegate past the base.
napalm-device-types v1.0 makes role bases declaration-only, so nothing shadows
anything and all seven forwarders are dead weight. Every method now resolves
straight to the mixin that implements it.
remove_package went with them: the base now calls the method by the name the
package mixin already used, uninstall_package, so the name adapter is gone too.
