I ran into two things while running this script.
1. The script as it exists in the git tree (Jeff Kirshers next-queue) is not
executable. I don't know if that's a patch issue or translation into the tree.
Easy enough to get around, but should probably be executable to start.
2. The script runs into a handful of errors,7 to be precise. I'm not sure if
they are real failures, incorrect expectations or maybe something in my kernel
.config (I have been using a minimal .config and enabling modules as needed.)
The output I get from it is:

----------------------------------------------------------------------------------------------------
The script sends messages to dmesg, most look to be informative "set" and
"unset" messages, but I do get a handful of failed messages. The dmesg queue
was cleared before the run so only contains the udp_tunnel-sh messages:
