These are still disabled by default since they require mac80211_hwsim changes that are not yet in the upstream kernel and because the test cases do not fully work yet. Anyway, they are quite convenient for development use, so good to have them available in the main repository. Signed-hostap: Jouni Malinen <j@w1.fi>
