Is there any -ve effect? 2) if i am going to increase it by 8 bytes then what will happen to net packet size and its data part? Is that all will fit in sk_buff? 3) Which is best to include my 2 fields in sk_buff or include its total value at end of data part? 4) When kernel passes the packet to dest host all sk_buff fields are also transferred or only packet header and data? parag. __________________________________ Do you Yahoo!?
