### 4.2.2 Device driver essential functions
### 4.2.2 Device driver product functions
A device driver manages the network interface on behalf of the host system, often presenting a standardized network device driver interface to the host operating system. It manages the transfer of data from the network interface to and from host memory. It carries out requests by the host software, such as configuration or loading firmware. It may keep and report statistics about network traffic.
A virtual network interface presents a network device driver interface to the rest of the host software. It may encrypt, filter, transform, route, discard, or otherwise modify network traffic entering the interface. The network traffic may then be directed to another virtual network interface on the same host, to another executable on the host, or to a physical network interface.
