Check for FT support when selecting FT suites
A driver supports FT if it either supports SME or the NL80211_CMD_UPDATE_FT_IES command. When selecting AKM suites, wpa_supplicant currently doesn't take into account whether or not either of those conditions are met. This can cause association failures, e.g., when an AP supports both WPA-EAP and FT-EAP but the driver doesn't support FT (wpa_supplicant will decide to do FT-EAP since it is unaware the driver doesn't support it). This change allows an FT suite to be selected only when the driver also supports FT. Signed-off-by: Matthew Wang <matthewmwang@chromium.org> Reviewed-by: Brian Norris <briannorris@chromium.org>
