> Interface operation mode
>
> ap (default) - interface operates as an access point
> station - interface acts as a client device, scanning for access points advertising the configured SSID
> station-bridge - interface acts as a client device and enables support for a 4-address frame format, so that the interface can be used as a bridge port
>
> The station-bridge mode, as implemented for 'wifi' interfaces, is incompatible with APs running the older 'wireless' package and vice versa.
