ND over WinVerbs is the end goal, however there are ND drivers in the field right now, supported by the various IB OEMs, that need to be fixed.  WinVerbs however is not supported currently in any driver release.

I could have sent the patch to just the OEMs and bypassed the mailing list, but I don't think splitting the code bases is a valuable thing to do.

I'm all for it.  However the OEM driver release cycle isn't gated on 2.1.  So this patch fixes existing bugs, without preventing a future change to WinVerbs.

Until ND support is available over WV, would be my guess.
