/**
* SECTION:nm-connection
* @short_description: Describes a connection to specific network or provider
*
* An #NMConnection describes all the settings and configuration values that
* are necessary to configure network devices for operation on a specific
* network. Connections are the fundamental operating object for
* NetworkManager; no device is connected without a #NMConnection, or
* disconnected without having been connected with a #NMConnection.
*
* Each #NMConnection contains a list of #NMSetting objects usually referenced
* by name (using nm_connection_get_setting_by_name()) or by type (with
* nm_connection_get_setting()). The settings describe the actual parameters
* with which the network devices are configured, including device-specific
* parameters (MTU, SSID, APN, channel, rate, etc) and IP-level parameters
* (addresses, routes, addressing methods, etc).
