s390: qeth driver connection hang
Frank Pavlic <fpavlic@de.ibm.com>
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.
