Awesome! What about the FQ-CoDel mac80211 patches themselves? I have a
tree where I've separated out the needed patches and rebased them on
mainline 4.4.9. Can I post that somewhere (or just email you the series)
and get you to include those as well? Or do I just dump the patch files
into the LEDE patches dir and send that as a patch to LEDE? (I see your
patch also refreshed subsequent patches; is there a script to do that
