From 1f8f7b7a7b885a0041a21b3d93c507269baf57c8 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Thu, 17 May 2007 16:32:39 +0300 Subject: IB/mlx4: Fix check of max_qp_dest_rdma in modify QP max_qp_dest_rdma is already in natural units - no need to shift. This was discovered by a test that deliberately requests more outstanding atomic operation than the device supports. Found by Sagi Rotem at Mellanox.
