 746      * Explicit equals method to compare the 'match' for flows stored in the data-stores and flow fetched from the switch.
 747      * Flow installation process has three steps
 748      * 1) Store flow in config data store
 749      * 2) and send it to plugin for installation
 750      * 3) Flow gets installed in switch
 751      *
 752      * The flow user wants to install and what finally gets installed in switch can be slightly different.
 753      * E.g, If user installs flow with src/dst ip=10.0.0.1/24, when it get installed in the switch
 754      * src/dst ip will be changes to 10.0.0.0/24 because of netmask of 24. When statistics manager fetch
 755      * stats it gets 10.0.0.0/24 rather then 10.0.0.1/24. Custom match takes care of by using masked ip
 756      * while comparing two ip addresses.
 757      *
 758      * Sometimes when user don't provide few values that is required by flow installation request, like
 759      * priority,hard timeout, idle timeout, cookies etc, plugin usages default values before sending
 760      * request to the switch. So when statistics manager gets flow statistics, it gets the default value.
 761      * But the flow stored in config data store don't have those defaults value. I included those checks
 762      * in the customer flow/match equal function.
