Hello Ming... > I want to debug a new ethernet driver.

Any sample code out there. I personally suggest to create new procfs/debugfs/sysfs entry, use it to modify a variable inside your driver. Then, based on this variable's value, act accordingly in your driver. For instruction on how to create procfs/sysfs/debugfs, you can refer to Linux Kernel Module programming guid (on tldp.org) or articles on Linux Weekly News (lwn.net).
