How should I process? Does this require a new patch version? If so, how can I submit it to this Gerrit change? https://gerrit.osmocom.org/c/libgtpnl/+/35985/comment/91d144f7_00135eaa PS1, Line 15: ./gtp-link add gtp0 ip6 --sgsn # IPv6 SGSN Dual stack is support for both inner MS IP address and outer GTP IP address. 1) Dual stack example for inner address: gtp-tunnel add gtp0 v0 1 10.141.10.2 b010::11 gtp-tunnel add gtp0 v0 1 a010:: b010::11 2) Dual stack example for outer GTP address (this requires two GTP devices, one gtp0 for IPv4 and one gtp1 for IPv6) gtp-tunnel add gtp0 v1 1 1 10.141.10.2 192.168.10.11 gtp-tunnel add gtp1 v1 1 1 10.141.10.2 a010:: b010::10 ... and it is possible to combine both, dual stack in inner MS IP address and outer GTP IP address.
