This is a problem with the rtl8723bs driver in staging; it's source tree has a custom IEEE80211 header which imports 'linux/ieee80211.h', but redefines many of the #define's from the original header. Functionally, they are the same, but I will submit a patch in reply to this email which removes the duplicate #defines from drivers/staging/rtl8723bs/include/ieee80211.h. It looks like there's also some #defines there that shadow enum members in 'linux/ieee80211.h', but I will address that in separate patch(es) when I have a chance.
