From 1557967bf921e787f0c9236c2899603d85f44d31 Mon Sep 17 00:00:00 2001 From: Vipul Pandya Date: Mon, 7 Jan 2013 13:11:52 +0000 Subject: [PATCH] RDMA/cxgb4: Display streaming mode error only if detected in RTS With later firmware, the chances of getting streaming mode data after we exit RTS is likely, so we don't need to warn for it. The only real case where we don't expect it is when the QP is in RTS. Move QP to ERROR when streaming mode data received.
