  "message": "RDMA/cxgb4: Fix QP flush logic\n\nThis patch makes following fixes in QP flush logic:\n\n- correctly flushes unsignaled WRs followed by a signaled WR\n- supports for flushing a CQ bound to multiple QPs\n- resets cidx_flush if a active queue starts getting HW CQEs again\n- marks WQ in error when we leave RTS. This was only being done for\n  user queues, but we need it for kernel queues too so that\n  post_send/post_recv will start returning the appropriate error\n  synchronously\n- eats unsignaled read resp CQEs. HW always inserts CQEs so we must\n  silently discard them if the read work request was unsignaled.\n- handles QP flushes with pending SW CQEs. The flush and out of order\n  completion logic has a bug where if out of order completions are\n  flushed but not yet polled by the consumer and the qp is then\n  flushed then we end up inserting duplicate completions.\n- c4iw_flush_sq() should only flush wrs that have not already been\n  flushed.  Since we already track where in the SQ we\u0027ve flushed via\n  sq.cidx_flush, just start at that point and flush any remaining.\n  This bug only caused a problem in the presence of unsignaled work\n  requests.\n\nSigned-off-by: Steve Wise \u003cswise@opengridcomputing.com\u003e\nSigned-off-by: Vipul Pandya \u003cvipul@chelsio.com\u003e\n\n[ Fixed sparse warning due to htonl/ntohl confusion.  - Roland ]\n\nSigned-off-by: Roland Dreier \u003croland@purestorage.com\u003e\n",
