Finally I success make mediatek wifi driver run on LEDE 🙂 But mediatek do not allow to public the source code, I have to upload it somewhere as blob.

Now I guess a lot of features could unlock now.

1. monitor mode.
LEDE mt76 driver is very slow, but mediatek official driver is fast and stable.

2. more than one ssid.
we can create one ssid named VoCore2 and one named VoCore2-Guest for host and guest. It supports up to 16 ssid.

3. low level wifi control.
normally we use this for certification like FCC, KC…Last time I have to use mediatek openwrt, but now we can directly use LEDE.
