The PR contains 2 commits: one fix to the datapath; the other e2e test which tests both the fix and the basic funtionatlity. The problem is the basic functionality part fails the e2e test. However, it is only reproducible in e2e test, not in dev cluster. We also included the same functionality in Anthos. I haven't figured out the reason.
You would need a Linux machine (Ubuntu is fine), and install virtualbox on the machine.
