Subject: [Intel-wired-lan] [iwl-next v2 2/2] ice: tc: allow ip_proto matching

Add new matching type for ip_proto.

Use it in the same lookup type as for TTL. In hardware it has the same
protocol ID, but different offset.

Example command to add filter with ip_proto:
$tc filter add dev eth10 ingress protocol ip flower ip_proto icmp \  skip_sw
action mirred egress redirect dev eth0
