Hi, Joe

I think there are lots of such cases in kernel, and I think it is a
legacy issue with some story in it.

The reason I only change the e1000e is that the patch I send before will
broken the style of e1000e, because it's using true and false, not 1 and 0.

I think this will be a huge work if we want to correct all these cases,
and I think the good way is to separate the work to small pieces and
finish them slowly.

Thanks,
Michael Wang
