Subject: [patch 3/5] [PATCH] qeth: support z/VM VSWITCH Port Isolation
Date: Wed, 20 May 2009 09:38:39 +0200 [thread overview]
Message-ID: <20090520073927.953030000@de.ibm.com> (raw)
In-Reply-To: 20090520073836.897878000@de.ibm.com
[-- Attachment #1: 614-qeth-port-isolation.diff --]
[-- Type: text/plain, Size: 3911 bytes --]
From: Ursula Braun <ursula.braun@de.ibm.com>
z/VM Virtual Switch Port Isolation allows guests on a VLAN UNAWARE
virtual switch to be isolated from other guests on the VSWITCH.
(See z/VM Apars VM64281 and VM64463).
The Linux qeth driver is affected, because it has to handle new
error codes introduced with the z/VM VSWITCH Port Isolation support.
