Subject: [PATCH 4.14 201/284] openvswitch: Fixed nd target mask field in the flow dump.
From: Martin Varghese <martin.varghese@...ia.com>
commit f19c44452b58a84d95e209b847f5495d91c9983a upstream.
IPv6 nd target mask was not getting populated in flow dump.
In the function __ovs_nla_put_key the icmp code mask field was checked
instead of icmp code key field to classify the flow as neighbour discovery.
