This script runs tests of all of Cake's flow isolation parameters (flowblind, hosts, srchost, dsthost, flows, dual-srchost, dual-dsthost, and triple-isolate).
Simply run it without arguments as root. Trust me! :)
srchost/dsthost stopped working due to a bug introduced in kernel 5.8 in this commit, so this demonstrates that bug, and confirms that the patch that was made for it works. In the future, we can re-run this test any time changes are made that may affect Cake's flow isolation.
