3363 * Remove the STA entry to ensure the STA PS state gets cleared and
3364 * configuration gets updated. This is relevant for cases, such as
3365 * FT-over-the-DS, where a station re-associates back to the same AP but
3366 * skips the authentication flow, or if working with a driver that
3367 * does not support full AP client state.
3369 * Skip this if the STA has already completed FT reassociation and the
3370 * TK has been configured since the TX/RX PN must not be reset to 0 for
3373 * FT-over-the-DS has a special case where the STA entry (and as such,
3374 * the TK) has not yet been configured to the driver depending on which
3375 * driver interface is used. For that case, allow add-STA operation to
3376 * be used (instead of set-STA). This is needed to allow mac80211-based
3377 * drivers to accept the STA parameter configuration. Since this is
3378 * after a new FT-over-DS exchange, a new TK has been derived, so key
3379 * reinstallation is not a concern for this case.
