Currently openwrt has an opensource driver mt76, I have a study about it, every line of its code is very clear and beautiful, so it should be easy to replace official mt7628 with this one, unfortunately, I find it is very hard to understand its registers(mtk did not document any of that registers) so I can not setting up its interfaces unless do some hack 🙂

There is another way, enable cfg80211 in mt7628, I find it has some code about cfg80211, but I enable it in makefile, it can not work at all 🙂 guess it is not well tested…
