The whole skb ll be deallocated in lieu to the way it is allocated in one go. If you mean just modifying the data then check skbuff.h for family of skb_pull/_push/_clone/_copy/ etc along with a memcpy. BTW take care of packet checksums at different layers. What exactly do you want to hack ? What is your goal?
