Subject: [PATCH/RFC 12/12] hack: rocker: no ip frag match

*** hack; for informational purposes only; not for upstream merge ***

Open vSwitch expects to match on the fragmentation state, however, the
of-dpa world of rocker does not implement such a field in its flow key. As
a work-around ignore it to allow testing (in the absence of fragments).
