>Description:

After flushing rules or reloading different set of rules, there may be need to have statistics of a different network or different traffic. This will require statistics values zeroed out and then restarted. users will then be able to see new statistics for new networks that are configured in NPF. There is currently no way of doing that unless after rebooting your machine.
>How-To-Repeat:

npfctl flush
npfctl stop

then join a different network 

npfctl reload

statistics show a count of old traffic and new traffic
>Fix:


npfctl stats needs a reset option to reset the statistics to zeros.

npfctl stats reset


This gives users the flexibility to manage their statistics however they want.
