Hmm.. OFED works on kernels that have compiled-in inline'd multicast map functions that do not include the pkey copy, while mainline's multicast map functions do. So to work around this there is a bit of code in OFED to overwrite the pkey in the multicast hw address. This means on OFED with those kernels ip maddr returns the wrong hw address sometimes..
