Adds support for -N/--config-nfc ethtool command for
configuring RX classfiers.

Currently only raw Ethernet (flow-type ether) matching is added
based on source/destination addresses and VLAN Priority (PCP).

The ALE policer engine is used to perform the matching and routing to
a specific RX channel.

Test cases:

Increase number of RX channels to 8
ip link set eth1 down
ip link set eth0 down
ethtool -L eth0 rx 8

1) Ether source address test
	ethtool -N eth0 flow-type ether src xx:yy:zz:aa:bb:cc action 5

  Traffic from that address should route to channel 5

2) Ether destination address test
	ethtool -N eth0 flow-type ether src yy:zz:aa:bb:cc:dd action 4

  Traffic to that address should route to channel 4

3) Drop test
	ethtool -N end0 flow-type ether src xx:yy:zz:aa:bb:cc action -1

  Traffic from that address should be dropped

4) VLAN PCP test

on Remote create VLAN with ID 5 and all traffic mapping to required priority to test. e.g. 7
	sudo ip link add link eno1 name eno1.5 type vlan id 5 egress-qos-map 0:7 1:7 2:7 3:7 4:7 5:7 6:7 7:7
	sudo ifconfig eno1.5 192.168.10.1

on DUT create VLAN with id 5
	ip link add link end0 name end0.5 type vlan id 5
	ifconfig end0.5 192.168.10.5

VLAN pcp 7 vid 5 route to RX channel 6
	ethtool -N end0 flow-type ether vlan 0xe005 action 6

  Traffic from that VLAN with PCP 7 should route to channel 6
