If possible, it would be helpful to have a comment in that example code about the re-arming since the impression I got from quickly looking at the l3fwd-power code is that interrupts are turned off because the app wants to poll for a threshold of time before “giving up” and turning interrupts back on again. I’m happy to open a pull request to add this comment, too, if you prefer.

The best is to submit a patch on the mailing list, Cc'in the relevant maintainers.
Thanks
