A good time to lobby for this might be, well a couple months ago, as they’re producing alpha builds for their upcoming 2.0 release with kernel 4.9 and new Cavium/Mediatek/Octeon SDKs. I just asked about the status in the EdgeRouter Beta forum, in case it finds the right eyes before the release:

This started a discussion, and no, so far it looks like there’s no BQL support in the upcoming 2.0 release.

For my own benefit, re-reading the original patch series comment (https://lwn.net/Articles/469652/ <https://lwn.net/Articles/469652/>) makes it sound like BQL is useful even without AQM (original benchmarks were done with straight pfifo_fast). I didn’t realize this, actually. If anything incorrect about BQL was said in this discussion, correct us, please… :)
