 * 3) WMA_SET_STA_BCASTKEY_RSP
 * Upon receipt of this message from HAL,

 * received by MLME while in the following state:
 * MLME state = eLIM_MLM_WT_SET_BSS_KEY_STATE --OR--
 * MLME state = eLIM_MLM_WT_SET_STA_KEY_STATE --OR--
 * MLME state = eLIM_MLM_WT_SET_STA_BCASTKEY_STATE

 * This is because, it appears that the handling of the
 * SETKEYS REQ is handled symmetrically on both the AP & STA
