1. When an IP packet is received from IP, do we get a chain of data ( as in
ifnet ) or is it a continuous buffer.

2. What is the use of the following fields in the sk_buff structure
1. data_skb pointer.
2. count.
3. users.

3. If we have to send a particular IP packet ( which is in sk_buff format )
to two diffrent destinations, do we have to duplicate the sk_buff.
Doesn't this reduce the performance.
Is there any other way to handle this case.
