This introduces a small helper in net/ethernet, which registers a network notifier at core_initcall time, and accepts registrations mapping expected asynchronously-probed network device paths (like, "usb1/1-1/1-1.1/1-1.1:1.0") and the MAC that is needed to be assigned to the device when it appears.The mac prefix is poor. I think eth_mac is better.
OK.

OK. Although different places in the kernel seem to have different expectations about that.

Right... I'll fix these and wait for more comments. Thanks again for the review. -Andy -- Andy Green | TI Landing Team Leader Linaro.org ?
