In linux kernel since version 2.6.18 (release Date: 2006-09-19)  

This module allows for capturing the changes to TCP connection
state in response to incoming packets. It is used for debugging
TCP congestion avoidance modules. If you don't understand
what was just said, you don't need it: say N.

Documentation on how to use TCP connection probing can be found

To compile this code as a module, choose M here: the
module will be called tcp_probe.
