Wireshark · Wireshark-dev: [Wireshark-dev] adding an encap_type_info element

[Lange Jan-Erik <Jan-Erik.Lange@xxxxxxxxxxxxxx>]

Hello,

 

I want to dissect a packet that is not ethernet compliant. In the following I decribe the strategy to realize this.
Can you tell me where I'm wrong?

 

1. I have to add a new encap_type_info element to the encap_table_base[] struct in the wtap.c file.
 /* WTAP_ENCAP_MYPHYLAYER */
 { "My Phy Layer", "myphylayer" },

 

2. In the wtap.h file I have to add a new #define element, ie.
#define WTAP_ENCAP_MYPHYLAYER                    129

 

3. Now I can add the dissecor:
dissector_add("myphylayer", WTAP_ENCAP_MYPHYLAYER, myprot_handle);

 

Is this correct in general or are there points missing?

 

Best regards
Jan
