The "Reply 'Done'" Button can be used by the developer making the changes, but it doesn't have to be. There just needs to be some indication that it's been addressed ("Reply Done" or a comment posted after another patch is uploaded is fine) to make the next review go faster. In this particular dissector's case, there were some "systematic" issues, which generated a large number of comments trying to point each instance out. For those, I don't think you need to do a "Reply Done" for each, a comment noting the "systematic change" after you update another patch is fine. For more of the "individual issues", you can use "Reply Done" or just make a general statement like "I believe all comments have been addressed". If you disagree or have questions on a particular comment, a "conversation" can be had with subsequent comments (that's usually easier than using the "general" comments section when talking about an issue.
