> This patch is meant to allow for RX network flow classification to insert
> and remove ethertype filter by ethtool
> 
> Example:
> Add an ethertype filter:
> $ ethtool -N eth0 flow-type ether proto 0x88F8 action 2
> 
> Show all filters:
> $ ethtool -n eth0
> 4 RX rings available
> Total 1 rules
> 
> Filter: 15
> 	Flow Type: Raw Ethernet
> 	Src MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
> 	Dest MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF
> 	Ethertype: 0x88F8 mask: 0x0
> 	Action: Direct to queue 2
> 
> Delete the filter by location:
> $ ethtool -N delete 15
