Yet again, sorry for the spam, still new to sending in patches and
everything related, but I'm more than happy being able to contribute.

Tried contacting the mentioned people in the relevant TODO, but after a
couple of weeks I still haven't received a response, thus sending this
to you directly. Error messages still need to be changed to use
netdev_err, but that's for another patch.
