2.6.33.3-85.fc13.x86_64
This my linux kernel version...
I am building linux raw socket with IP_HDRINCL to send raw ip packet .. But kernel is not sending the packets with ipv4 MF flag set on. Kernel reassembels all the fargment then send the whole packet to network.. and if i dont send the last fragment kernel does not sending any packet at all..
Actually my question is how to force kernel to send the packet with MF flag set on through raw socket...
PLz dont give answer like fedora EOL.... plz comment ASP if anyone have any idea...

The raw socket means that you have to handle everything, such as IP header. That means that your application take care of fragment and set MF flag.

But I am in situation where I am doing all the things myself but kernel is not sending any packet until the last packet being send..which means kernel is not putting the packet into the network with MF flag set on. This bug has been fixed in kernel version 2.6.36 .. Now what I am thinking is how I can patch my kernel to remove the bug.. I want to do this just for learning how kernel patch can be made and install them.. any good tutorial link to know this stuff??

This is relative to build a new kernel. The steps are dependent on distribution. I did it on Fedora. You can refer this to find out how to rebuild your kernel with patch. Following link is for Fedora.
