Add logic to obtain the mtu from the network PCO parameter and set it to kernel when the mobile data connection is established. When there is no PCO mtu configured from the network, the mtu size defined in the corresponding APN will be used. In case no mtu size is defined for an APN used for data connection, the MCC/MNC based MTU defined in the framework overaly will be applied. bug:17046179 Change-Id: I6465d4b8f2076aaa380ae3617fb3f24adbe136d4
