Title:
   mlx5 EN driver wrongly enables sets VLAN filtering under promiscuous
  mode

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Wily:
  Fix Released
Status in linux source package in Xenial:
  Fix Released

Bug description:
  Description of problem: The mlx5 Ethernet driver doesn't allow packets
  marked with all possible VLAN tags to be accepted under promiscuous
  mode. This is wrong and disallows Open-Stack to properly function in
  Para-Virtual configuration.

  
  How reproducible: 

   just put the NIC to promiscuous mode and send packet from another
  node tagged any vlan which was not previously configured on the NIC
  vlan filter, it will not be accepted.

  
  Actual results:
  ARP packets sent on vlan 52 packets are dropped 

  Expected results:
  packets should received 

  Host info:
  #uname -a
  Linux dev-h-vrt-006 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  #lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 15.10
  Release:        15.10
  Codename:       wily

  
  The following upstream commit fix it:

  commit c07543431e9f3d126d083808efa0e76461d8833b

      net/mlx5e: Disable VLAN filter in promiscuous mode

      When the device was set to promiscuous mode, we didn't disable
      VLAN filtering, which is wrong behaviour, fix that.

      Now when the device is set to promiscuous mode RX packets
      sent over any VLAN (or no VLAN tag at all) will be accepted.

  I backported it to Ubuntu 15.10 (please see the attached patch). This
  issue need to be fix also in Ubuntu 14.04.4 not only 15.10.
