Bug Description
We have had customer reports of kernel hangs related to MLX4. Mellanox has addressed the issue with the following two patches:
fed91613c9dd ("net/mlx4_en: Avoid scheduling restart task if it is already running")
ba603d9d7b12 ("net/mlx4_en: Handle TX error CQE")
Microsoft would like to request these two commits in all releases supported on Azure.

Hi Joe, both patches you requested were backported to linux stable, and hence they came
organically to our Ubuntu kernels; they are already available to azure kernels in the following
versions (both currently in -proposed):
4.15.0.1107
5.4.0-1040
They're also available in version 5.8 , for the main kernel - the rebase work for Azure is ongoing
and should be completed soon, I'll let you know when that happens.
Thanks!
