Subject: Universal tap device

Hi all.                                                                  

Looking at macvtap and thinking about the tap solutions in general, I    
think it would be handly to have some universal tap device.              

This could use rx_handler to hook onto any netdev and provide chardev    
tap-like iface to it. Using that, one can just hook onto macvlan device  
and macvtap would not be needed.                                         

This would allow other scenarios like vxlan-tap, vlan-tap, bond-tap or   
whatever.                                                                

Does this idea seem to be reasonable?                                    

Thanks                                                                   

Jiri
