From 69a3ffaa0a43d1c5a34b6f52aa08a5fc3d8d87d4 Mon Sep 17 00:00:00 2001 From: Jan Sokolowski <jan.sokolowski@intel.com> Date: Tue, 14 Nov 2017 04:34:45 -0800 Subject: [PATCH] IB/hfi1: Use 4096 for default active MTU in query_qp Currently, if a port is queried that has an invalid Maximum Transmission Unit, driver reports default MTU of 2048. This in incorrect. Use default value of 4096 if invalid.
