    To reach this path you need to run the equivalent of:
    ip link set eth0 name eth1

    I have seen this a bit and my memory is that the error is generally
    harmless. It is trying to create a symlink with the same name as the
    directory or something like that. Which makes with one setting of
    CONFIG_SYSFS_DEPRECATED but not the other.

    So I don't believe this is a driver bug, and I suspect the renames
    come from using something like /etc/mactab which forces ethernet
    devices with specific mac addresses to specific ethernet device

    With whatever is sitting in my development tree I'm pretty certain
    this error isn't present. I don't recall if I did anything specific
    to fix this though. In particular I don't recall if this still
    happens with gregkh's queued sysfs patches applied.
