Subject: [patch 2/2] [PATCH] qeth: Use blkt defaults for OSA Express 4
Date: Mon, 23 Apr 2012 09:21:42 +0200 [thread overview]
Message-ID: <20120423072158.645482656@de.ibm.com> (raw)

[-- Attachment #1: 601-qeth-blkt-defaults.diff --]
[-- Type: text/plain, Size: 950 bytes --]
From: Stefan Raspl <raspl@linux.vnet.ibm.com>
The previous blkt defaults for OSA Express 4 cards produced inadequate
performance for streaming workloads. The present patch will apply a
set of more appropriate defaults.
