Pending on Sean's approval, basically my take is that the code should
be queued to 2.6.21 and then integrated right away into OFED 1.2. So
any ipoib testing would excersize the ipoib/ib_sa changes, the are
very few little changes expected, mostly an "ipoib interop" patch of
two lines removing from cma.c the setting on an "rdmacm signature bit"
at the mgid and usage of its own qkey.
