From 92761cdaf215599a1bd81d383facb32adabfa620 Mon Sep 17 00:00:00 2001 From: Joachim Fenkes Date: Wed, 9 May 2007 13:48:01 +0200 Subject: IB/ehca: Correctly set GRH mask bit in ehca_modify_qp() The driver needs to always supply the "GRH present" flag to the hypervisor, whether it's true or false. Not supplying it (i.e. not setting the corresponding mask bit) amounts to a "perhaps", which we don't want.
