Hi,
    	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
    interface.
    	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 vsgupta@cs.uiuc.edu,
    then that would be great.
Thanks a lot, Vijay
