packet reception by virtual network interface
i would like to know how can a virtual network interface be used to receive packets...i read Allesandro Rubini's article on Virtual Network Interface which states that as such interfaces have no hardware they cannot hv interrupts and consequently cannot be used for packet reception.
But the concept of bridging also creates a virtual interface which receives all the packets. How does bridging do that?
Also, how is it possible to pass a packet from the driver to the virtual interface instead of the IP layer??
