OK, at first step, as its 2.6.26-rc7 now, we will move forward with 
these patches for 2.6.27, that is send you a fixed patch set that 
addresses the other comments and will cover the changes needed for 
kernel consumers, namely ipoib to take advantage of this.

There was some discussion over this list in the past on exposing qp 
creation flags to user space, with the context being 
block-multicast-loop, XRC, low latency QPs, etc (see 
http://lists.openfabrics.org/pipermail/general/2008-March/048435.html).

I suggest that we will continue that thread and try to reach a consensus 
what's the correct way to allow these changes without too much pain.
