[ipfire-2.x.git] / src / patches / suse-2.6.27.39 / patches.arch / s390-02-06-qeth-offset.patch

From: Gerald Schaefer <geraldsc@de.ibm.com>
Subject: qeth: fix offset error in non prealloc header path
References: bnc#434333,LTC#48840

Symptom:     bad or no VSWITCH/guest lan network traffic
Problem:     Offset error in the non prealloc header path
Solution:    For the non preallocated qeth header code path we should not
             change the header length.
