Title:
  ixgbe and iproute2: inconsistent behaviour when setting VF mac and
  vlan using 'ip link'

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  'ip link' behaves strangely when trying to set both vlan and mac for a
  VF.

  Consider the following example:

  $ sudo ip link set p2p1 vf 6 mac 36:c3:25:02:65:c4 vlan 300
  $ ip link show p2p1
  189: p2p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
      link/ether 0c:c4:7a:1e:ac:0e brd ff:ff:ff:ff:ff:ff
      vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 2 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 3 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 4 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 5 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 6 MAC 36:c3:25:02:65:c4, spoof checking on, link-state auto

  As you can see, it was able to set MAC address, but silently ignored VLAN setting.
  Now comes the interesting part, if I specify vlan first and then mac, things work:

  $ sudo ip link set p2p1 vf 6 vlan 300 mac  36:c3:25:02:65:c5
  $ ip link show p2p1
  189: p2p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
      link/ether 0c:c4:7a:1e:ac:0e brd ff:ff:ff:ff:ff:ff
      vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 2 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 3 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 4 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 5 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
      vf 6 MAC 36:c3:25:02:65:c5, vlan 300, spoof checking on, link-state auto
