You did same thing and created "flush" and "get" root level commands
this time.

For get, existing "show port #P .." can be used:
"show port #P queue-region"

For flush, what do you think:
"set port #P queue-region flush (on|off)" ?

For port_id other than i40e, this call should return "Not supported",
not success. There are samples to this usage can you please check them?
