Doug, please consider this patch set for 4.13.
Saeed, care to get this into your testing environment?

This patch set is aiming to automatically find the optimal
queue <-> irq multi-queue assignments in storage ULPs (demonstrated
on nvme-rdma) based on the underlying rdma device irq affinity
settings.

Changes from v6:
- rebased on top of doug's for-4.13-mlx-shared 

Changes from v5:
- updated change log for patch #2
- removed nit indentation changes

Changes from v4:
- removed mlx5e assumptions on device home node irq affinity mappings
- rebased to 4.12-rc5

Changes from v3:
- Renamed mlx5_disable_msix -> mlx5_free_pci_vectors for symmetry reasons

Changes from v2:
- rebased to 4.12
- added review tags

Changes from v1:
- Removed mlx5e_get_cpu as Christoph suggested
- Fixed up nvme-rdma queue comp_vector selection to get a better match
- Added a comment on why we limit on @dev->num_comp_vectors
- rebased to Jens's for-4.12/block
- Collected review tags

Sagi Grimberg (7):
  mlx5: convert to generic pci_alloc_irq_vectors
  mlx5e: don't assume anything on the irq affinity mappings of the
    device
  mlx5: move affinity hints assignments to generic code
  RDMA/core: expose affinity mappings per completion vector
  mlx5: support ->get_vector_affinity
  block: Add rdma affinity based queue mapping helper
  nvme-rdma: use intelligent affinity based queue mappings
