   Where is options field stored in sk_buff

   Both ip and tcp header can contains options field. I am wondering where is   
   options field stored in kernel packet data structure sk_buff?   
      
   Originally, I thought the data should be inside sk_buff->cb. When I spoof a   
   tcp timestamp options packet and use loadable kernel module to print out the   
   sk_buff->cb. The sk_buff->cb are all zero. Any idea where does options field   
   stored in sk_buff?   
      
   Thanks for any response
