Subject: [MAINLINE 0/2] Enable DIM for legacy ULPs and use it in RDS

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.

Håkon Bugge (2):
  RDMA/core: Enable legacy ULPs to use RDMA DIM
  rds: ib: Add Dynamic Interrupt Moderation to CQs
