igb: support RX flow classification by VLAN priority
This patch is meant to allow for RX network flow classification to insert
and remove VLAN priority filter by ethtool
Example:
Add an VLAN priority filter:
$ ethtool -N eth0 flow-type ether vlan 0x6000 vlan-mask 0x1FFF action 2 loc 1
Show all filters:
$ ethtool -n eth0
4 RX rings available
Total 1 rules
Filter: 1
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: 0x0 mask: 0xFFFF
VLAN EtherType: 0x0 mask: 0xffff
VLAN: 0x6000 mask: 0x1fff
User-defined: 0x0 mask: 0xffffffffffffffff
Action: Direct to queue 2
Delete the filter by location:
$ ethtool -N delete 1
