Multiple SSIDs: possible or not?

I would like to configure BPI R2 as AP with two SSIDs (one SSID for permanent connection through a VPN tunnel). But hostapd configuration with bss directive fails and “iw list” returns “interface combinations are not supported”, while “iw list” for wireless chips with hardware support for multiple SSIDs should show “valid interface combinations” section. It is stated in and

Is it possible to have multiple SSID with BPI R2 or its hardware is incompatible?
