[ Upstream commit 116138c3bd34f92e550431d495db515f5ea19f13 ]
Commit 6e2baa44c6d1 ("staging: rtl8712: remove enum WIFI_FRAME_SUBTYPE") was wrong because: WIFI_DATA_NULL != IEEE80211_STYPE_NULLFUNC WIFI_DATA_CFACK != IEEE80211_STYPE_DATA_CFACK WIFI_DATA_CFPOLL != IEEE80211_STYPE_DATA_CFPOLL WIFI_DATA_CFACKPOLL != IEEE80211_STYPE_DATA_CFACKPOLL
the WIFI_DATA_xxx definitions include WIFI_DATA_TYPE, which is 'BIT(3)'. Restore the previous behavior by adding the missing 'IEEE80211_FTYPE_DATA |' (0x0008, that is to say BIT(3)) when these values are used.
Hopefully, the wrong commit was small enough and hand review is possible.
