From 8ec1077b35359c973f4b1de7c516be570a6df495 Mon Sep 17 00:00:00 2001 From: Bryan O'Sullivan Date: Thu, 15 Mar 2007 14:44:55 -0700 Subject: IB/ipath: Change packet problems vs chip errors handling and reporting Some types of packet errors are moderately common with longer IB cables and large clusters, and are not reported with prints by other IB HCA drivers. This suppresses those messages unless the new __IPATH_ERRPKTDBG bit is set in ipath_debug. Reporting of temporarily disabled frequent error interrupts was also made clearer We also distinguish between chip errors, and bad packets sent or received in the wording of the messages.
