This is a good observation, but the objective of my patch is to remove
unused defines so it will be easier to do the work that you mention. wifi.h
and ieee80211.h redefine a few kernel provided values, and I intend to
follow up by addressing all of them in one go.

Would you be willing to ack this patch as is?
