srv6-mobile: Support GTP4/6.DT and User Plane message mapping
Support the following new features in srv6-mobile. 1. GTP4.DT 2. GTP6.DT 3. User Plane Message encoding based on draft-murakami-dmm-user-plane-message-encoding-01 4. Add SRv6 mobile test cases Type: feature Signed-off-by: Tetsuya Murakami <tetsuya.mrk@gmail.com> Change-Id: I890e5171bf03513d54b4830f01b9dc7f47fe7c48 Signed-off-by: Tetsuya Murakami <tetsuya.mrk@gmail.com>
