/**
 * Test resulting IP address format with given APN settings.
 *
 * This test utility function performs following steps:
 *
 *   1) set "ril.data.apnSettings" to a given settings object,
 *   2) enable data connection and wait for a "datachange" event,
 *   3) check the IP address type of the active network info,
 *   4) disable data connection.
 *
 * Fulfill params: (none)
 * Reject params: (none)
 *
 * @param aApnSettings
 *        An APN settings value.
 * @param aIsIPv6
 *        A boolean value indicating whether we're expecting an IPv6 address.
 *
 * @return A deferred promise.
