  v2: Remove the "debug" module parameter as per Andrew Lunns suggestion.
    It's not really needed as ethtool msglvl can control that.

Linux users sometimes need an easy way to check current values of module
parameters. For example the module may be manually reloaded with different
parameters. Make these visible and readable in the /sys filesystem to allow
that.

It is normal to places comments like the above under the ---. In its
current place, it will be part of the commit message. Under the --- it
gets dropped when the patch is applied.
