The PTX flavour canutils[1] have a useful utility for generating a
sequence of CAN frames with an incrementing payload and checking such a
sequence for missed and reordered frames.
Recently, it has helped finding a regression in the kernel pfifo_fast
qdisc, which led to reordered frames[2].
To bring the utility to a greater audience, import the current state[3]
of it into the linux-can set of utilities.

The can-j1939 kernel part only follows & validates inbound & outbound
address claim packets. Jacd implements the part that chooses an address
and emits the address claim packet.
