Well, it's possible, but it would require more advanced debugging :) I would<br>
patch/kprobe the kernel to printk() messages at these 2 points:<br>
<br>
1. tcp_send_window_probe()<br>
2. tcp_v4_rcv()<br>
<br>
for the connection in question and checked the gap between the real repair-off<br>
and the response.<br>
