skb_put doesn't put anything in the area shown as
"skb_put area" in the diagram.
It
just updates sk_buff's pointers to allow you to write data in the skb_put
area.
The
skb_put call returns you the pointer to the start of this area, where you are
supposed to
write
whatever you want to (till length len which you gave in skb_put
call).
cheers,
Deepankar.

hi ,
i already read that articale but it is not having clear explaination about how actually in kernel it works?
what i am not getting from diagram 3 and 4 is that what exactly has been put in skb in diagram 4 so that it looks like
| headroom | data area| skb_put area | tailroom
from diagram 3
| headroom | data area | tailroom
regards,
parag.
