Thanks for your information. If "external_auth" means only offloading SAE
authentication to SME of wpa_supplicant and hostapd (driver should hook
cfg80211_ops. external_auth() to achieve this kind of offloading).
Then it is not the same as the job done by this patch.
This patch fully leverages SME of wpa_supplicant and hostapd.
