From a4c48a2691189cec0359ac13b41726d3005ef2f5 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Wed, 2 May 2007 15:17:11 +0200 Subject: s390: qeth driver connection hang Frank Pavlic Connection hangs when using EDDP mode because sk_protocol 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.
