title: FATAL: Module tcpprobe not found
body: <p>I'm currently working on DCTCP in Mininet. I get the code from github.<a href="https://github.com/mininet/mininet-tests" rel="nofollow">https://github.com/mininet/mininet-tests</a>
  I follow the README and install the dctcp kernel. But when running the code, the said
  FATAL: Module tcpprobe not found. 
  I check the path /lib/modules/3.2.18-dctcp/kernel/net/ipv4 and there is no tcp_probe.ko 
  So what should I do?</p>
  
  <p>I find that the tcp_probe is the kernel module so is that means the dctcp kernel I installed have something wrong?</p>
