Subject: [PATCH 2.6.37 04/11] RDMA/cxgb4: Ignore TERMINATE CQEs
Date: Fri, 10 Sep 2010 11:15:04 -0500 [thread overview]
Message-ID: <20100910161503.6829.32566.stgit@build.ogc.int> (raw)
In-Reply-To: <20100910161442.6829.91594.stgit-T4OLL4TyM9aNDNWfRnPdfg@public.gmane.org>
T4 incorrectly inserts TERM CQEs into the CQ. Silently ignore them.
