From a533eba6682f1dc89bfa5dc6e16e18ea257dd4d0 Mon Sep 17 00:00:00 2001 From: Dennis Dalessandro Date: Fri, 2 May 2014 11:40:17 -0400 Subject: [PATCH] IB/ipath: Translate legacy diagpkt into newer extended diagpkt commit 7e6d3e5c70f13874fb06e6b67696ed90ce79bd48 upstream. This patch addresses an issue where the legacy diagpacket is sent in from the user, but the driver operates on only the extended diagpkt. This patch specifically initializes the extended diagpkt based on the legacy packet.
