Subject: [PATCH for-next v3 0/2] Introduce rdma_set_min_rnr_timer() and use it in RDS

ib_modify_qp() is an expensive operation on some HCAs running
virtualized. This series removes two ib_modify_qp() calls from RDS.

I am sending this as a v3, even though it is the first sent to
net. This because the IB Core commit has reach v3.

Håkon Bugge (2):
  IB/cma: Introduce rdma_set_min_rnr_timer()
  rds: ib: Remove two ib_modify_qp() calls
