[openib-general] [PATCH RFC] return qp pointer as part of ib_wc

BTW, I just pushed this IPoIB CM code out to staging.
I'll post an updated patch RSN for -mm inclusion, but meanwhile
you can look at an example here:
git://git.openfabrics.org/git/~mst/linux-2.6/.git ipoib_cm_branch_2_6_20

Look under drivers/infiniband/ulp/ipoib/ipoib_cm.c
