Re: At which Network Layer

? 2013?04?10? 16:42, Robert Clove ??:

Hello All,

There is a field in sk_buff structure name clone which tell whether the sk_buff structure has been cloned or not?

I want to know at which layer does this clonning happen at L2,L3 or L4. any layer when it is needed. you can check function: net/core/sk_buff.c: skb_clone(), it is called in drivers, L3(like ip), and L4(like tcp).

Thanks
