> ntuple-filter feature on/off:
> Default is on. If turned off, the filters will be removed from both PF and iavf
> list. The removal is irrespective of current filter state.
> 
> Steps to reproduce:
> -------------------
> 
> 1. Ensure ntuple is on.
> 
> ethtool -K enp8s0 ntuple-filters on
> 
> 2. Create a filter to receive the traffic into non-default rx-queue like 15 and
> ensure traffic is flowing into queue into 15.
> Now, turn off ntuple. Traffic should not flow to configured queue 15.
> It should flow to default RX queue.
