 754     /**
 755      * Explicit equals method to compare the 'match' for flows stored in the data-stores and flow fetched from the switch.
 756      * Usecase: e.g If user don't set any ethernet source and destination address for match,data store will store null for
 757      * these address.
 758      * e.g [_ethernetMatch=EthernetMatch [_ethernetDestination=null, _ethernetSource=null, _ethernetType=
 759      * EthernetType [_type=EtherType [_value=2048], _mask=null, augmentation=[]]
 760      *
 761      * But when you fetch the flows from switch, openflow driver library converts all zero bytes of mac address in the
 762      * message stream to 00:00:00:00:00:00. Following string shows how library interpret the zero mac address bytes and
 763      * eventually when translator convert it to MD-SAL match, this is how it looks
 764      * [_ethernetDestination=EthernetDestination [_address=MacAddress [_value=00:00:00:00:00:00], _mask=null, augmentation=[]],
 765      * _ethernetSource=EthernetSource [_address=MacAddress [_value=00:00:00:00:00:00], _mask=null, augmentation=[]],
 766      * _ethernetType=EthernetType [_type=EtherType [_value=2048], _mask=null, augmentation=[]]
 767      *
 768      * Similarly for inPort, if user/application don't set any value for it, FRM will store null value for it in data store.
 769      * When we fetch the same flow (with its statistics) from switch, plugin converts its value to openflow:X:0.
 770      *  e.g _inPort=Uri [_value=openflow:1:0]
 771      *
 772      * So this custom equals method add additional check to take care of these scenario, in case any match element is null in data-store-flow, but not
 773      * in the flow fetched from switch.
 774      *

 776      * @param storedFlow
