/**
 * SECTION:nm-setting-8021x
 * @short_description: Describes 802.1x-authenticated connection properties
 *
 * The #NMSetting8021x object is a #NMSetting subclass that describes
 * properties necessary for connection to 802.1x-authenticated networks, such as
 * WPA and WPA2 Enterprise Wi-Fi networks and wired 802.1x networks.  802.1x
 * connections typically use certificates and/or EAP authentication methods to
 * securely verify, identify, and authenticate the client to the network itself,
 * instead of simply relying on a widely shared static key.
 *
 * It's a good idea to read up on wpa_supplicant configuration before using this
 * setting extensively, since most of the options here correspond closely with
 * the relevant wpa_supplicant configuration options.
 *
 * Furthermore, to get a good idea of 802.1x, EAP, TLS, TTLS, etc and their
 * applications to Wi-Fi and wired networks, you'll want to get copies of the
 * following books.
