I want to send two different ethernet frames . So, I want to send via tap in tunnel.py.

Do I need to create two tap device in tunnel.py.
My assumption,  is create two tap using open_tun_interface() method.
then bind that two tap interfaces.

Once Ethernet frames comes, receive through tap devices and need to send to USRP board in two separate channels using ofdm.
In usrp, I have two daughter boards, so i can send two ofdm modulated signal.

here my problem is ,

how to give two separate streams into to USRP.
How to set transmit and receive path.
How at the receiver side can I proferly get the frames and arrage.

For example, if I send a tcp file stream , I need to get and store the file at receiver properlly.

Please provide any idea on this.
