[ofa-general] IPOIB CM (NOSRQ) patches

[Pradeep Satyanarayana]

I have incorporated the IPOIB CM (NOSRQ) review comments and subsequent
discussions on this mailing list into a couple of patches (to follow).

The first patch will be V5 of the NOSRQ patch.

The second patch will be an extension of the NOSRQ patch, to
handle the corner case of running out of RC QPs. In that case
this patch enables switching to UD mode. Existing RC QPs should
remain unaffected.
