Is there a concern that the mechanism allows for DoS? How do they mitigate the situation that the author describes?

If you have standard compliant hardware, pause is point to point, not broadcast. You can configure hosts to ignore pause and also to not generate it; although it may be difficult to configure an embedded device, so you probably need to fix the switch or replace it with something that works.

Accidental pause frame DoS has been observed in the wild and AFAIK there's no known solution.
