hello Micha,
i will explain you what i did now. i add a call in between ip_finish_output to ip_finish_output2. like ip_finish_output will call add_my_header that will actally add my header then pass that skb to ip_finish_output2.
Is that correct way to add new protocol?
I have few questions on skbuff can you please answer to that it is necessary for me?
1) what is use of unsigned char *raw ?
2) what are the importance of unions at each layer? and what they not contains ethernet header in each unions?
3) where does received packets ethernet header is removed? (hat ment...)
4) what is the cache header concept i.e hh_cache?
Thanking you.
Parag.
