Subject: Get TOS from IP header

Hi All,

I want  to get the TOS field content from IP header at 
my application which is using SCTP protocol.
I know that it can be done by Using RAW socket but 
There is a over head of implementing the sctp at the 
Application layer . 
Is there a better way of getting a TOS field filled
Which we received from IP header.

I taught of adding code in kernel to recognize a socket option at the kernel,
If this option is set just and get TOS contents in receive .

Please let me know if this is the way to go about it or is there 
A better way to achieve the same .

Thanks and Regards
Naveen
