What's with the byte order marks here?

It's important that people are able to see how to disable LRO.  Using a
different name for it, and no module parameter description, really doesn't
help.

You should also implement ethtool get_flags and set_flags methods so that
LRO can be turned on and off later (at least once the ethtool command gets
patched, hint hint).
