Hello Marc,
I did some more testing with different CAN-USB adapters and feel pretty
comfortable on the below patch set now.
Would you think this is something for can-next?
If so, I would also start to extend the can-gw.

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).
Btw. here are still some patches that haven't been pushed upstream.
Best,
Oliver
