  [Impact]
  When enabling SR-IOV on Mellanox devices and setting vxlan tunnel over the PF device (adding vxlan port to an OVS bridge),
  the kernel is crashing as result of the unimplemented ndos: .ndo_{add,del}_vxlan_port

  [Fix]
  This issue was fixed in upstream kernel:
  9737c6a net/mlx4_en: Add VXLAN ndo calls to the PF net device ops too

  ~/linux$ git describe --contains 9737c6ab7afbc950e997ef80cba2c40dbbd16ea4
  v3.18-rc6~9^2~12

  I've backported it to 3.16 (by removing the "yet to be introduced"
  ndo_gso_check) and attached the backported version here.

  The patch was built and tested on top of ubuntu-trusty: abb1293
  ("UBUNTU: Ubuntu-lts-3.16.0-29.39~14.04.1")

  [Test Case]
  Use the affected Mellanox device w/ an Ubuntu 3.16 kernel. Setup vxlan tunnel over PF device. This should succeed.
