How to send a tcp packet to same machine from a kernel module by creating a sk_buff struct

Hi all,

Can somebody tell me or point me to correct resource .
I want to know how can i send a fabricated TCP packet from my kernel
module using
sk_buff . So basically how do i create this struct, make it look like a
sk_buff having incoming
tcp packet on some device and add it to queue from which sk_buff are
processed by upper layers. So kernel TCP layer should see it as normal
packet.

Thanks,
