Hi guys when n why the following occurs
<1>Unable to handle kernel NULL pointer dereference at virtual address 00000194
<1>Unable to handle kernel paging request at virtual address d2971f6c
Here I was making a copy of skb(objct of sk_buff) and retransmit it immediatly using tcp_transmit_skb() function of tcp_output file
i.e I want send the same packet repeatedly.....
