Hi,

In the USB perforce project there are Giant free USB ethernet drivers, which 
have been around for quite a while. I am currently in the run-up renaming 
symbols so that my new USB stack can co-exist with the old USB stack. At 
least it will be possible to compile a kernel with both USB stacks.

I suppose that USB ethernet drivers will no longer be available in the old USB 
stack ?
