From c49298026908a8ce9dcf01ed68734ad171cef98b Mon Sep 17 00:00:00 2001 From: Ira Weiny <ira.weiny@intel.com> Date: Wed, 27 Jul 2016 21:08:42 -0400 Subject: [PATCH 11/18] IB/hfi1: Allow for non-double word multiple message sizes for user SDMA Git-commit: c49298026908a8ce9dcf01ed68734ad171cef98b Patch-mainline: v4.8-rc1 References: FATE#321231 FATE#321473, bsc#1040698 The driver pads non-double word multiple message sizes but it doesn't account for this padding when the packet length is calculated. Also, the data length is miscalculated for message sizes less than 4 bytes due to the bit representation in LRH. And there's a check for non-double word multiple message sizes that prevents these messages from being sent. This patch fixes length miscalculations and enables the functionality to send non-double word multiple message sizes.
