iavf: Support Ethernet Type Flow Director filters
Support the addition and deletion of Ethernet filters.
Supported fields are: proto
Supported flow-types are: ether
Example usage:
ethtool -N ens787f0v0 flow-type ether proto 0x8863 action 6
ethtool -N ens787f0v0 flow-type ether proto 0x8864 action 7
