Station mode of IEEE 802.11r is currently supported only with drivers
that use SME from wpa_supplicant.

Same here, i.e., this drivers that implement SME are not currently
supported in IEEE 802.11r station mode with the nl80211 driver
interface. There is some ongoing work in this area, but nothing complete
