Currently, OCV self-capability is being set into the RSN supplicant state machine only during the initial connection and never getting updated. But for the driver-SME cases the driver may enable/disable OCV in (Re)Association Request frame RSNE based on the AP chosen to roam. This will lead to missing synchronization between wpa_supplicant and the driver. Thus, update OCV self-capability in the wpa_supplicant RSN state machine based on the (Re)Association Request frame RSNE indicated in the connect response.
