-// EffectiveConnectionType is the connection type whose typical performance is
-// most similar to the measured performance of the network in use. In many
-// cases, the "effective" connection type and the actual type of connection in
-// use are the same, but often a network connection performs significantly
-// differently, usually worse, from its expected capabilities.
-// EffectiveConnectionType of a network is independent of if the current
-// connection is metered or not. For example, an unmetered slow connection may
-// have EFFECTIVE_CONNECTION_TYPE_SLOW_2G as its effective connection type. The
-// effective connection type enums are be in increasing order of quality.
