*
* Description:
* Returns the optimal filterlist to reduce the filter handling in the

* to register or unregister a can_filter in the filter lists.
*
* A filter matches in general, when
*
* <received_can_id> & mask == can_id & mask
*
* so every bit set in the mask (even CAN_EFF_FLAG, CAN_RTR_FLAG) describe
* relevant bits for the filter.
*
* The filter can be inverted (CAN_INV_FILTER bit set in can_id) or it can
* filter for error frames (CAN_ERR_FLAG bit set in mask). For error frames
* there is a special filterlist and a special rx path filter handling.
*
* Return:
* Pointer to optimal filterlist for the given can_id/mask pair.
* Constistency checked mask.
* Reduced can_id to have a preprocessed filter compare value.
