I do not see anything wrong in the code. rtifconfig seems to ask the
IFF_PROMISC flag to be set for the driver, and the driver code seems
to take this flag into account. So I guess you will have to trace
the path from rtifconfig to the driver code to see where the
information gets lost.

Note that what you are doing here is enabling the rtcap interface
(which is a plain linux interface, and not the rtnet interface), you
may want to avoid doing that in a first step, in case it fiddles
with the promisc bit too.
