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")
