I'll also state that we need both patches, but there's no point pushing
my original patch (to allow EEE to be disabled) unless Laurent is going
to also submit a patch to make use of the flag - the EEE disable and
Laurent's patch needs to be part of a series. We don't merge stuff that
adds facilities that have no users, because that's been proven time and
time again to be a recipe for accumulating cruft.

So, at the moment, "net: stmmac: provide flag to disable EEE" ain't
going anywhere until there's a patch that makes use of the new flag.
