Subject: [PATCH 1/5] s390: fix connection hang in qeth
Date: Mon, 30 Apr 2007 17:41:20 +0200 [thread overview]
Message-ID: <20070430154120.GA23666@de.ibm.com> (raw)
From: Ursula Braun <braunu@de.ibm.com>
Frank Pavlic <fpavlic@de.ibm.com>
Connection hangs when using EDDP mode because sk is NULL
when skb has been copied via skb_copy. This results in dropping
packets.
Also keep MAC address after recovery of Virtual NICs so that
traffic can flow again and duplicate statements in
qeth_dev_set_route_store removed.
