Bug description:
  The operators are promoting "Carrier Aggregation"[1] as the latest
  network capability. The capability should be visible when the user is
  connected to the LTE-Advanced network.

  1) ril interface from mtk supports the extended radio type

   // Same as the value in TelephonyManager.java
   enum NetworkType {
    NETWORK_TYPE_UNKNOWN = 0,
    NETWORK_TYPE_GPRS = 1,
    NETWORK_TYPE_EDGE = 2,
    NETWORK_TYPE_UMTS = 3,
    NETWORK_TYPE_CDMA = 4,
    NETWORK_TYPE_EVDO_0 = 5,
    NETWORK_TYPE_EVDO_A = 6,
    NETWORK_TYPE_1xRTT = 7,
    NETWORK_TYPE_HSDPA = 8,
    NETWORK_TYPE_HSUPA = 9,
    NETWORK_TYPE_HSPA = 10,
    NETWORK_TYPE_IDEN = 11,
    NETWORK_TYPE_EVDO_B = 12,
    NETWORK_TYPE_LTE = 13,
    NETWORK_TYPE_EHRPD = 14,
    NETWORK_TYPE_HSPAP = 15,
    NETWORK_TYPE_GSM = 16,
   };

   // MTK extend radio tech see ServiceState.java
   enum RadioTechExt {
    RIL_RADIO_TECHNOLOGY_MTK = 128,
    RIL_RADIO_TECHNOLOGY_HSDPAP, //129
    RIL_RADIO_TECHNOLOGY_HSDPAP_UPA, //130
    RIL_RADIO_TECHNOLOGY_HSUPAP, //131
    RIL_RADIO_TECHNOLOGY_HSUPAP_DPA, //132
    RIL_RADIO_TECHNOLOGY_DC_DPA, //133
    RIL_RADIO_TECHNOLOGY_DC_UPA, //134
    RIL_RADIO_TECHNOLOGY_DC_HSDPAP, //135
    RIL_RADIO_TECHNOLOGY_DC_HSDPAP_UPA, //136
    RIL_RADIO_TECHNOLOGY_DC_HSDPAP_DPA, //137
    RIL_RADIO_TECHNOLOGY_DC_HSPAP, //138
    RIL_RADIO_TECHNOLOGY_LTEA //139
   };

  2) ofono should support a new radio bearer type

  (ofono trunk)
  +const char *packet_bearer_to_string(int bearer)
  +{
  + switch (bearer) {
  + case PACKET_BEARER_NONE:
  + return "none";
  + case PACKET_BEARER_GPRS:
  + return "gprs";
  + case PACKET_BEARER_EGPRS:
  + return "edge";
  + case PACKET_BEARER_UMTS:
  + return "umts";
  + case PACKET_BEARER_HSUPA:
  + return "hsupa";
  + case PACKET_BEARER_HSDPA:
  + return "hsdpa";
  + case PACKET_BEARER_HSUPA_HSDPA:
  + return "hspa";
  + case PACKET_BEARER_EPS:
  + return "lte";
  + }
  + return "";
  +}

  3) indicator-network should add LTEA support with a new icon

  (0.7.1+15.04.20160304-0ubuntu1 )
  static Modem::Bearer str2technology(const QString& str)
  {
   if (str.isEmpty() || str == "none")
    return Modem::Bearer::notAvailable;
   if (str == "gprs")
    return Modem::Bearer::gprs;
   if (str == "edge")
    return Modem::Bearer::edge;
   if (str == "umts")
    return Modem::Bearer::umts;
   if (str == "hspa" || str == "hsupa" || str == "hsdpa")
    return Modem::Bearer::hspa;
   if (str == "hspap")
    return Modem::Bearer::hspa_plus;
   if (str == "lte")
    return Modem::Bearer::lte;

   qWarning() << PRETTY_FUNCTION << ": Unknown techonology" << str;
   return Modem::Bearer::notAvailable;
  }
