RE: About the alternation of skbuff

Hi all,

Could you tell me how can I point to the data content in skbuff
(TCP header)?  I've read the files in the net directory, but I'm 
a bit confused how can I point to the data content of tcp 
header.  And while I'm reading one of the files, I don't know 
why tcp_header_size have to be shift by 2
  
In the file of tcp_output.c

	th->doff = (tcp_header_size >> 2);

Would you mind telling me the reason behind that?


Thanks a lot

your sincerely,
 
marco.
