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.

Apologies for the noise and for the wrong initial commit :(
