Hi Kevin, I had already looked into that. The thing is that I am confused over the data portion of packets with the data room in skbuff. It seems to me that these pointers (head,data,tail,end) are just used for manipulating the way you would want to insert data (including packet headers, msghdr, etc) into skbuff. However, just before sending out a normal IP packets, where would the pointers be pointing at?? That's what I am unsure of. :P Cheers, Jonathan -----Original Message----- From: owner-kernelnewbies@nl.linux.org [mailto:owner-kernelnewbies@nl.linux.org] On Behalf Of Kevin Wojtysiak Sent: Wednesday, October 10, 2001 11:05 PM To: kernelnewbies@nl.linux.org Subject: Re: regarding about sk_buff ....
