One of my card is:

011:00:0: Intel 82599 (SFI/SFP+) 10 GbE Controller (ethernet network, revision 0x01)

It's the same as yours.

On my machine:

        capabilities=fff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx>

        inet6 fe80::21b:21ff:fe9b:4ed6%ixg1 prefixlen 64 scopeid 0x4

vlan8: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx>
        capabilities=7ff80<TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx>
        capabilities=7ff80<TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
        enabled=0
        vlan: 8 parent: ixg1
        address: 00:1b:21:9b:4e:d6
        input: 3 packets, 260 bytes
        output: 9 packets, 702 bytes, 5 multicasts
        inet 10.0.0.2 netmask 0xff000000 broadcast 10.255.255.255
        inet6 fe80::21b:21ff:fe9b:4ed6%vlan8 prefixlen 64 scopeid 0x6

and "ping 10.0.0.2" from other machine makes vlan8's input counter
increments.

 Could you test again?
