From 13ee429a0271b997f57b22ee67d40fc601f0b220 Mon Sep 17 00:00:00 2001 From: Feras Daoud Date: Wed, 28 Dec 2016 14:47:26 +0200 Subject: [PATCH] IB/ipoib: Use debug prints instead of warnings in RNR WC status If a receive request has not been posted to the work queue, the incoming message is rejected and the peer will receive a receiver-not-ready (RNR) error. In IPoIB, IB_WC_RNR_RETRY_EXC_ERR error is part of the life cycle therefore ipoib_cm_handle_tx_wc function will print to debug instead of warnings.
