net/can/j1939 has had no in-tree selftests. This series adds a kselftest suite for the J1939 socket layer and the TP/ETP transport, run on vcan with a CAN_RAW socket as an independent on-the-wire peer.
The whole suite runs on vcan under QEMU and passes. Two limits span the series and are left for follow-up: the transport timers are checked only with wide windows, not tight bounds, and the ETP abort/timeout edge cases are not covered yet (the abort/timeout tests are TP only).
