  * has arrived. To work-around this issue, we keep two groups of message
  * objects whose partitioning is defined by C_CAN_MSG_OBJ_RX_SPLIT.
  *
- * If CONFIG_CAN_C_CAN_STRICT_FRAME_ORDERING = y
- *
- * To ensure in-order frame reception we use the following
- * approach while re-activating a message object to receive further
- * frames:
- * - if the current message object number is lower than
- *   C_CAN_MSG_RX_LOW_LAST, do not clear the NEWDAT bit while clearing
- *   the INTPND bit.
- * - if the current message object number is equal to
- *   C_CAN_MSG_RX_LOW_LAST then clear the NEWDAT bit of all lower
- *   receive message objects.
- * - if the current message object number is greater than
- *   C_CAN_MSG_RX_LOW_LAST then clear the NEWDAT bit of
- *   only this message object.
- *
- * This can cause packet loss!
- *
- * If CONFIG_CAN_C_CAN_STRICT_FRAME_ORDERING = n
- *
  * We clear the newdat bit right away.
  *
  * This can result in packet reordering when the readout is slow.
