of-flow: match criteria (ipv6-source,ipv6-destination) different in config and operational db

odl:
version.properties
org.opendaylight.controller.version = 0.1
org.opendaylight.controller.build.scm.version = 2fffd8cdb3ed75f478b900c677bb4d97e5e91c9c
org.opendaylight.controller.build.user = jenkins-controller

test: mininet 2.1.0 + ovs 2.0.0

steps:
1) PUT xml /restconf/config/opendaylight-inventory:nodes/node/openflow:${switch_idx}/table/${table_id}/flow/${flow_id}
(xml file f101.xml in attachment)

2) GET its operational state (for full details see f101odb.xml in attachment)
3) GET its config

4) seen difference
config:
<ipv6-destination>fe80:2acf:e9ff:fe21::6431/94</ipv6-destination>
<ipv6-source>1234:5678:9ABC:DEF0:FDCD:A987:6543:210F/76</ipv6-source>

operational:
<ipv6-source>1234:5678:9ABC:DEF0:FDC0:0000:0000:0000/-1</ipv6-source>
<ipv6-destination>FE80:2ACF:E9FF:FE21:0000:0000:0000:0000/-1</ipv6-destination>
