From 45e354e3f235ecb51e16576d6668c43cddbb6e68 Mon Sep 17 00:00:00 2001 From: Alexander Schmidt Date: Tue, 16 Feb 2010 08:59:50 +0000 Subject: [PATCH] IB/ehca: Require in_wc in process_mad() If the caller does not pass a valid in_wc to process_mad(), return MAD failure status, as it is not possible to generate a valid MAD redirect response (and redirects are the only MAD responses ehca generates).
