s390: qeth: wrong packet length in qdio header
Packets Length in qdio header is broken when using EDDP on Layer2 devices. This leads to skb_under_panic on receiver system when running on z/VM GuestLAN devices. Signed-off-by: Frank Pavlic <fpavlic@de.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
