Bug description:
  While deploying a VM in D series (D8S_V3 and D16S_V3) and enabling
  accelerated networking, MLX5 drivers are getting installed.  However,
  accelerated networking is not showing as enabled in guest OS. The same
  VM is showing enabled from portal.

  
  The problem is in the Mellanox driver for the CX-4 VF.  Mellanox has already 
fixed the problem in three separate patches, which are all in mainline.

  We would like to request the following three commits in all supported
  releases:

  2f5438ca0ee0 ("net/mlx5: Tidy up and fix reverse christmas ordring")
  c268ca6087f5 ("net/mlx5: Expose port speed when possible")
  dc392fc56f39 ("net/mlx5: Expose link speed directly")
