Re: what is the driver of vm's virtual ethernet?

[Stephen Hemminger <stephen@xxxxxxxxxxxxxxxxxx>]

What happens is that real (or virtual) network devices call the common network receive function - netif_receive_skb

This function has a hook rx_handler which is called if the device is part of a bridge.

The bridge code the processes the packets and either floods them, redirects, or drops the packets

based on the learned forwarding table.
