discribe debug tunnel

i searce for a describing for the command "debug tunnel". I got the output:

Feb 21 17:24:58.800: Tunnel3: GRE/IP encapsulated 2.32.192.81->2.32.128.81 (linktype=7, len=438)

Feb 21 17:24:58.976: Tunnel3: GRE/IP to decaps 2.32.128.81->2.32.192.81 (len=64 ttl=252)

Feb 21 17:24:58.980: Tunnel3: GRE decapsulated IP 2.0.1.11->2.16.0.222 (len=40, ttl=62)

Have someone a specification for the field linktype ?

Thanks ...
