Are you sure about that? What does

systemctl status NetworkManager.service 

says?

Be aware that with NetworkManager > 9.8.6, the ifnet plugin is not longer supported with systemd, since it conflicts wih OpenRC. The ebuild tells you then that you probably will need to reconfigure your networks:

                        ewarn "Ifnet plugin won't be used with systemd support enabled"
                        ewarn "as it is meant to be used with openRC and can cause collisions"
                        ewarn "(like bug #485658)."
                        ewarn "Because of this, you will likely need to reconfigure some of"
                        ewarn "your networks."

Regards.
