	I have been trying to build a protocol
similar to TCP within the Linux kernel for a 
mobile computing environment. 

	For that, I need to look at the list of
unacknowledged sk_buffs in order to change their
headers so that I can send them through a new 

	I have tried sk->send_head, sk->send_tail
but without any success. In spite of there being
around 36-37 unacknowledged segments, there is 
still nothing which I get by following the next 
or prev pointers of send_head and send_tail.

	Can anyone help me tell which other place
I can look into ?

	Any help will be greatly appreciated. If 
you can also cc the reply to,
then that would be great.

Thanks a lot, Vijay
