This way, the IP address / route handling between TUN devices and kernel GTP can be shared, which will provide not only a unified codebase but also a more consistent behavior. This also paves the road for to use kernel GTP from sgsnemu in the future. Related: OS#3214 Change-Id: Ic53a971136edd0d8871fbd6746d7b0090ce3a188
