Julian Wiedmann ec2c672632 s390/qeth: fix L3 next-hop in xmit qeth hdr ... On L3, the qeth_hdr struct needs to be filled with the next-hop IP address. The current code accesses rtable->rt_gateway without checking that rtable is a valid address. The accidental access to a lowcore area results in a random next-hop address in the qeth_hdr. rtable (or more precisely, skb_dst(skb)) can be NULL in rare cases (for instance together with AF_PACKET sockets). This patch adds the missing NULL-ptr checks.
