Description: qeth: fix L3 next-hop im xmit qeth hdr
Symptom: wrong destination address in qdio header
Problem: 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).
Solution: Add the missing NULL-ptr checks.
Reproduction: AF_PACKET program sending raw data
Upstream Commit:

== SRU Justification ==
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).
The solution is to add the missing NULL-ptr checks, which is done by commit ec2c6726322f.
Commit ec2c6726322f is in mainline as of v4.13-rc5, so this fix is only needed in Xenial.
== Fix ==
ec2c6726322f ("s390/qeth: fix L3 next-hop in xmit qeth hdr")
== Regression Potential ==
Low. Limited to s390.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
