Hello,

In my protocol, one TLV is called "proto" and contains the IANA number
of a well-known protocol. How can I display the value together with the
string and using the available data from <epan/ipproto.h>, for example?

I know how to do it via val_to_str() but I am failing on importing the
existing definitions.
See epan/dissectors/packet-rohc for 2 examples of how to access ipproto_val_ext from your dissector. ( from an hf[] array entry or using val_to_str_ext()).
