Abstract

What is disclosed is a method for interfacing applications to network driver interface device drivers. The method includes the steps of binding a virtual device driver to a network driver interface; filling in a network driver interface request structure; and, passing the network driver interface request structure to the network driver interface. An apparatus for interfacing applications to network driver interface device drivers is also disclosed.

Claims

1. A method comprising:

binding a virtual device driver to a network driver interface;

filling in a network driver interface request structure; and

,

passing said network driver interface request structure to said network driver interface.

2. The method of claim 1, further comprising:

creating a device level query based on said network driver interface request structure; and

,

transferring said device level query to a device driver.

3. The method of claim 2, wherein said transferring transfers said device level query to a cable modem driver.

4. The method of claim 2, further comprising:

interpreting said device level query; and

,

sending one of a command and a query to a network interface.

5. The method of claim 4, wherein said command is sent if a configuration is to be set in said network interface;

and said query is sent if information is being requested.

6. The method of claim 4, further comprising:

returning a status result indicator to said network driver interface.

7. The method of claim 4, further comprising:

filling in said network driver interface request structure; and

,

returning said network driver interface request structure to said virtual device driver.

8. An apparatus comprising:

a processor;

a memory coupled to said processor, and configured to cause said processor to;

bind a virtual device driver to a network driver interface;

fill in a network driver interface request structure; and

,

pass said network driver interface request structure to said network driver interface.

9. The apparatus of claim 8, wherein said memory is further configured to cause said processor to:

create a device level query based on said network driver interface request structure; and

,

transfer said device level query to a device driver.

10. The apparatus of claim 9, wherein said memory includes a cable modem driver and is further configured to cause said processor to transfer said device level query to said cable modem driver.

11. The method of claim 9, wherein said memory is further configured to cause said processor to:

interpret said device level query; and

,

send one of a command and a query to a network interface.

12. The method of claim 11, wherein said memory is further configured to cause said processor to send said command if a configuration is to be set in said network interface;

and send said query if information is being requested.

13. The method of claim 11, further comprising the step of:

return a status result indicator to said network driver interface.

14. The method of claim 11, wherein said memory is further configured to cause said processor to:

fill in said network driver interface request structure; and

,

return said network driver interface request structure to said virtual device driver.

15. A machine readable medium having stored thereon instructions which when executed by a processor cause the machine to perform operations comprising:

binding a virtual device driver to a network driver interface;

filling in a network driver interface request structure; and

,

passing said network driver interface request structure to said network driver interface.

16. The machine readable medium of claim 15 having stored thereon further instructions which when executed by a processor cause the machine to perform further operations comprising:

creating a device level query based on said network driver interface request structure; and

,

transferring said device level query to a device driver.

17. The machine readable medium of claim 16, wherein transferring causes the machine to perform operations comprising:

transferring said device level query to a cable modem driver.

18. The machine readable medium of claim 16 having stored thereon further instructions which when executed by a processor cause the machine to perform further operations comprising:

interpreting said device level query; and

,

sending one of a command and a query to a network interface.

19. The machine readable medium of claim 18, wherein said command is sent if a configuration is to be set in said network interface;

and said query is sent if information is being requested.

20. The machine readable medium of claim 19 having stored thereon further instructions which when executed by a processor cause the machine to perform further operations comprising:

returning a status result indicator to said network driver interface.

21. The machine readable medium of claim 16 having stored further instructions thereon which when executed by a processor cause the machine to perform further operations comprising:

filling in said network driver interface request structure; and

,

returning said network driver interface request structure to said virtual device driver.
