From 7d3a7b9ea59ddb223aec59b45fa1713c633aaed4 Mon Sep 17 00:00:00 2001 From: Lijun Pan Date: Fri, 12 Feb 2021 20:49:00 -0600 Subject: ibmvnic: skip send_request_unmap for timeout reset Timeout reset will trigger the VIOS to unmap it automatically, similarly as FAILVOER and MOBILITY events. If we unmap it in the linux side, we will see errors like "30000003: Error 4 in REQUEST_UNMAP_RSP". So, don't call send_request_unmap for timeout reset.
