igb: support RX flow classification by ethertype
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
