From 0540bbbe455e123a1692d26205ad1a29983883b0 Mon Sep 17 00:00:00 2001 From: Hoang-Nam Nguyen Date: Fri, 10 Oct 2008 14:40:39 -0700 Subject: [PATCH] IB/ehca: Don't allow creating UC QP with SRQ This patch prevents a UC QP to be created attached to an SRQ, since current firmware does not support this feature.
