From 450bb3875f5f5ab3679823c941d6045d16967370 Mon Sep 17 00:00:00 2001 From: Patrick Marchand Latifi Date: Wed, 20 Feb 2008 19:08:10 -0800 Subject: [PATCH] IB/ipath: Reset the retry counter for RDMA_READ_RESPONSE_MIDDLE packets Reset the retry counter when we get a good RDMA_READ_RESPONSE_MIDDLE packet. This fix will prevent the requester from reporting a retry exceeded error too early.
