I did some tests:
* Applied the patch
* Modified my driver
* Modified drivers/net/can/dev.c:can_changelink() to force the
CAN_CTRLMODE_CC_LEN8_DLC on (this is just me being lazy to do it
from userland).
* Modified cansend and candump from can-utils to be able to
respectively send and print DLCs greater than 8.
* Set up two channels can0 and can1 and connected those to the same
bus.
* Ran 'cangen can0' and 'candump any' simultaneously.
Results of candump:
