FWIW, this is the question I ask before accepting OFED kernel patches
into our kernel.  With the exception of SDP (which was intentionally
allowed) and qlgc_vnic (which was unintentionally allowed), if it's not
either in the upstream linux kernel, or slated for inclusion, then I
don't include it in our kernel.  Hence why xrc and rds support still
isn't in our products.
