Date: Wed, 08 Feb 2012 11:19:49 +0100 [thread overview]
Message-ID: <20120208102029.571724964@de.ibm.com> (raw)
In-Reply-To: 20120208101944.272235343@de.ibm.com
[-- Attachment #1: 606-qeth-query-osa-table.diff --]
[-- Type: text/plain, Size: 6301 bytes --]
From: Frank Blaschka <frank.blaschka@de.ibm.com>
Add qeth device private ioctl to query the OSA address table.
This helps debugging hw related problems.
