- * This file implements objects to access interfaces.
- * Externally, interfaces are represented by three structures:
- * + struct netdev_dev, representing a network device,
- * containing e.g. name and a refcount;
- * We can have private variables by embedding the
- * struct netdev_dev into our own structure
- * (e.g. netdev_dev_bsd)
- *
- * + struct netdev, representing an instance of an open netdev_dev.
- * The structure contains a pointer to the 'struct netdev'
- * representing the device.
- *
- * + struct netdev_rx, which represents a netdev open to capture received
- * packets. Again, private information such as file descriptor etc. are
- * stored in our own struct netdev_rx_bsd which includes a struct
- * netdev_rx.
- *
- * 'struct netdev', 'struct netdev_dev', and 'struct netdev_rx' are referenced
- * in containers which hold pointers to the data structures. We can reach our
- * own struct netdev_XXX_bsd by putting a struct netdev_XXX within our own
- * struct, and using CONTAINER_OF to access the parent structure.
