From 0666eb06ab12b1f876719ff5b7d39cf3c609dec3 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Tue, 19 May 2009 21:38:39 +0000 Subject: qeth: support z/VM VSWITCH Port Isolation 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.
