       org.freedesktop.NetworkManager.Connection.Active:
 
       Objects that implement the Connection.Active interface represent an
       attempt to connect to a network using the details provided by a Connection
       object. The Connection.Active object tracks the life-cycle of the
       connection attempt and if successful indicates whether the connected
       network is the "default" or preferred network for access. NetworkManager
       has the concept of connections, which can be thought of as settings, a
       profile or a configuration that can be applied on a networking device.
       Such settings-connections are exposed as D-Bus object and the
       active-connection expresses this relationship between device and
       settings-connection. At any time a settings-connection can only be
       activated on one device and vice versa. However, during activation and
       deactivation multiple active-connections can reference the same device or
       settings-connection as they are waiting to be activated or to be
       deactivated.

         Reload:
         @flags: optional flags to specify which parts shall be reloaded.
 
         Reload NetworkManager's configuration and perform certain updates, like flushing a cache or
         rewriting external state to disk. This is similar to sending SIGHUP to NetworkManager but it
         allows for more fine-grained control over what to reload (see @flags). It also allows
         non-root access via PolicyKit and contrary to signals it is synchronous.
 
         No flags (0x00) means to reload everything that is supported which is identical to
         sending a SIGHUP.
         (0x01) means to reload the NetworkManager.conf configuration from disk. Note that this
         does not include connections, which can be reloaded via Setting's ReloadConnections.
         (0x02) means to update DNS configuration, which usually involves writing /etc/resolv.conf
         anew.
         (0x04) means to restart the DNS plugin. This is for example useful when using
         dnsmasq plugin, which uses additional configuration in /etc/NetworkManager/dnsmasq.d.
         If you edit those files, you can restart the DNS plugin. This action shortly interrupts
         name resolution.
         Note that flags may affect each other. For example, restarting the DNS plugin (0x04)
         implicitly updates DNS too (0x02). Or when reloading the configuration (0x01), changes
         to DNS setting also cause a DNS update (0x02). However, (0x01) does not involve restarting
         the DNS plugin (0x04) or update resolv.conf (0x02), unless the DNS related configuration
         changes in NetworkManager.conf.
