That's a strange output. Where does the "40000" come from? Maybe you are
using an old version of the "ip" program. The command shown below should
report:

  # ip link help
  ...
  TYPE := { vlan | veth | vcan | dummy | ifb | macvlan | can }

If you don't see "can", it's the wrong version.

The device must be started to have the interrupt line requested. Please read

http://lxr.free-electrons.com/source/Documentation/networking/can.txt#L747

on how to use the "ip" program for CAN.

Your tools seem not to work properly. What does

 # canconfig can0

print out? Anyway, please try using "ip" in the first place.

Please do not repeat the same question multiple times. It does usually
not help in getting an answer more quickly.
