Title:
  Kernel crash when setting vxlan tunnel over the mlx4_en when acting as
  PF

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Eyal Perry (~eyalpe) writes:

  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 crushing as result of the unimplemented ndos: .ndo_{add,del}_vxlan_port

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