The Dynamic Interrupt Moderation mechanism can only be used by ULPs
using ib_alloc_cq() and family. We extend DIM to also cover legacy
ULPs using ib_create_cq(). The last commit takes advantage of this end
uses DIM in RDS.

I would much prefer if you could move RDS off that horrible API finally
instead of investing more effort into it and making it more complicated.
