Hi Leonhard,
thanks for reaching out.
Would you be interested in this code? If you are, how can I contribute it? It currently lives inside a git branch on my machine.
We're happy to review + merge your patch, please submit it using gerrit, see https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit
If you have troubles setting that up, and it's just a small patch, and you don't expect to contribute more in the future, you can also simply use git send-email to send the patch [series] to this mailing list.
Regards, Harald
