Harald Welte gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/1882 gtp-kernel: Fix tunnel creation/removal for GTP Version 1 When Linux Kenrel GTP-U support is enabled, OpenGGSN so far only worked with GTPv0,but not with GTPv1, as the TEI values were not correctly configured. This patch fixes the initialzation of the local and remote TEI before using libgtpnl to create a tunnel context in the kernel.
