* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma:
  IB/rxe: Don't check for null ptr in send()
  IB/rxe: Drop future atomic/read packets rather than retrying
  IB/rxe: Use BTH_PSN_MASK when ACKing duplicate sends
  qedr: Always notify the verb consumer of flushed CQEs
  qedr: clear the vendor error field in the work completion
  qedr: post_send/recv according to QP state
  qedr: ignore inline flag in read verbs
  qedr: modify QP state to error when destroying it
  qedr: return correct value on modify qp
  qedr: return error if destroy CQ failed
  qedr: configure the number of CQEs on CQ creation
  i40iw: Set 128B as the only supported RQ WQE size
  IB/cma: Fix a race condition in iboe_addr_get_sgid()
  IB/rxe: Fix a memory leak in rxe_qp_cleanup()
  iw_cxgb4: set correct FetchBurstMax for QPs
