I don't know what you would expect from connecting RDS to a TUNTAP 
interface. With TUNTAP you create a virtual Ethernet interface, which 
allows you to connect your transceiver to the Linux network stack.
For RDS, I don't see any benefit from doing this.

What you might want is connect the transceiver to Wireshark to inspect 
and dissect the data. This can be done with RFtap:
