I tested this with and without the patch and it's inconclusive:

1. tcpdump sees foreign packets with and without patch
2. tcpdump -p sees foreign packets with and without patch

This oddly enough matches my expectation that nobody raised issues about
promisc not working so far, but it leaves the question if we are/I am testing the
right thing?
