About auto-applying "add ra0/rai0 to br-lan", I have searched for a while. The conclusion is that to apply this configuration, the sbin/mtkwifi tool does not provide a direct function for it; instead, it relies on the "vif_enable" function from mtkwifi.lua. Therefore, I need to make an HTTP request at startup, for example, using curl -s http://127.0.0.1/cgi-bin/luci/admin/network/wifi/vif_enable/ra0. However, at present, there is an issue with authentication or logging in to perform this action.
