can: populate netdev::dev_id for udev discrimination
My objective is to be able to totally discriminate CAN ports on multi-port cards via udev so as to rename them to semantically interesting/unique names for my system (e.g., "ecuCAN" and "auxCAN" instead of "can0" and "can1"). The following patch assigns the dev_id field to match the channel number on all multi-channel devices. I can only test my two-port Peak PCI card, but it works as expected: ATTRS{dev_id} now expresses the port number and my udev rules now unambiguously pick out and rename my individual CAN ports.
