I guess in particular IFF_LOOPBACK means that all packets from
a device will come right back to the current machine, and go
nowhere else.

That usage sounds completely different then the CAN usage which
appears to mean.  Broadcast packets will be returned to this machine
as well as being sent out onto the wire.
