Introduce improved DLC handling for Classic CAN with introduces a new element 'len8_dlc' to the struct can_frame and additionally rename the 'can_dlc' element to 'len' as it represents a plain payload length. Before implementing the CAN_CTRLMODE_CC_LEN8_DLC handling on driver level this patch set cleans up and renames the relevant code. No functional changes. This patch set is based on mkl/linux-can.git (testing branch).
