Hi Doug,

the RDMA code was developed for a GPLed driver and moved to the code,
and lots of people contributed to it under the GPL, as they assumed
Linux code in genral is.  Іf dual-licensing is possible at all it would
require a lot of work, which I don't think is worth it.  If you don't
want GPL code in the core rdma.ko module we can move it to a rdma-gpl.ko
module, but that would be a little bit odd.
