Right now the tests are quite simple - based off the shell scripts and 
topology here: https://bitbucket.org/nw-swin/caia-mptcp-files/src

These are mostly quick and dirty tests to catch regressions (I'm still 
making some fairly broad changes to the implementation). They provide 
basic MP connections and some dummynet control to adjust the link 
characteristics.

I don't yet have anything where I can easily script-in topology changes, 
bring links up and down mid-connection, introduce cross traffic, etc... 
but the plan is to move to that kind of set up.

And it's probably worth mentioning I've just been running my tests in 
VMs, though I'd like to run tests on hardware once I squash some of the 
stability issues.

cheers,
nigel
