I want to access the time-to-live (TTL) of each packet (or flow). According to https://www.open-mesh.org/projects/batman-adv/wiki/Fragmentation-technical, it is located in the common header, but I was not able to find the command to retrieve the TTL.
Batman-adv common header
Compatibility version, packet type, and time-to-live
Could you please show me how to access the TTL information? Thank you very much in advance!
