I'd love to try this out.  I'm using a Netgear FA120 USB ethernet adapter
with the axe driver, and my kernel panics with a page fault in
usb_transfer_complete every time I attempt to bring the interface down.
This means I can't reboot without a panic.
It looks like this code might address my problem.

I've never tested a patch in this manner before though.  I assume there's
some utility like mergemaster to merge this into my existing code.  If
somebody can tell me how to merge in these changes I'll try them out this
week and let you know how it goes.
