- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance

- Bind_device() associates a device driver with a particular socket.

- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the

- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.

+ It looks up the specified device ID in the list of registered
+ drivers, binds it to the socket, and tries to create an instance

+ Bind_device() associates a device driver with a particular socket.

+ a newly inserted card. An instance of that driver will then be
+ eligible to register as a client of this socket.
+
+ Register_client() uses the dev_info_t handle to match the
+ caller with a socket. The driver must have already been bound
+ to a socket with bind_device() -- in fact, bind_device()
+ allocates the client structure that will be used.
