+ * Commonly used across update_owe request and event interfaces.
+ *
+ * @bssid: BSSID of the peer from which the OWE processing has to be done.
+ * @status: status code, %WLAN_STATUS_SUCCESS for successful OWE info

+ *	    cannot give you the real status code for failures. Used only for
+ *	    OWE update response command interface (user space to driver).
+ * @ie: IE's obtained from the peer or constructed by the user space. These are
+ *	    the IE's of the remote peer in the event from the host driver and
+ *	    the constructed IE's by the user space in the request interface.
+ * @ie_len: Length of IE's in octets.
