Is this still incomplete? Does 50% mean that it works in 64 bit LEDE?
The latest LEDE img that came out for brcm 2710 (rpi3) a few hours ago says its 64 bit so, since this is one of 2 total raspi 3 operating systems released in 64 bit (The only other is Gentoo 64 for rpi 3 that came out ~1 month ago i think) I would love to give it a try.
The only thing holding me back is i currently use my pi3 as an wireless AP with Librelec. They have a really cool setting where you can share the pi eth0 port with the devices wlan0 to create a wifi ap.
I think they use the debian package "connman" as the backend for this functionality
