To force wpa_supplicant to use the nl80211 frame injection API, as opposed to needing a monitor interface. For some reason NL80211_FEATURE_SK_TX_STATUS is not set on android (no issues on pc using the same compat-drivers).

This might be a bug with Android's libnl implementation? So, perhaps this isn't a wpa_s bug, and we need to do more investigation to isolate the root cause.
