+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: qeth: unregister MAC addresses during recovery.
+References: bnc#484767,LTC#52200
+
+Symptom: After thousands of recovery cycles no more MAC addresses are
+registered at z/VM GuestLAN adapter.
+Problem: MAC address table of GuestLAN adapter full.
+Solution: Unregister MAC addresses from device (layer 2) during
+recovery cycle. When the device is set online the MAC
+addresses are registered again on the device.
