It's mainly for debugging. Not all values are guaranteed to mean the
same thing for different versions of tinc. However, options c means
PMTUDiscovery and ClampMSS is enabled for this node, status 01c2 means
the node has a valid session key, is using SPTPS and has a working UDP
connection.

Note that some of that information can be seen in a human-friendly form
using the info command.  For example, try:

tinc -n routers info 10_254_5_11
