+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: qeth: avoid skb_under_panic for malformatted inbound data
+References: bnc#434333
+
+Symptom:     kernel dump
+Problem:     malformatted inbound packets due to hardware problems
+Solution:    make the qeth driver more robust in case of malformatted inbound
+             packets due to hardware problems, an additional check for
+             OSN-card-type is added for OSN-type packets.
