I think you've got a pretty good solution at the moment, and this current issue is just an odd insertion from Asus upstream. I sent a PR to revert the 802.1q line after studying it some more.A starting point would probably be to look at the code with KMO's original PRs without any of the following Asus or GPL changes, and see if that runs properly as a basepoint. If it does, then consider this as being "forked away from Asus" (like my OpenVPN code) and no longer merge subsequent changes by Asus unless they make clear sense in our context.
I flashed stock 46065 on the AC68U and notice that they don't really bother with any download traffic at least pre-HND. Their iptables chains are slightly different, so they may have thought their mark 6 was useful, but with the existing Merlin modifications, it didn't make sense.
Learned a lot about the old AC68U today, and how to tcpdump 802.1q traffic.
