Let me know when it's in the mlx5-next tree to pull. It needs to go to -rc... This needs a mlx5-rc branch for this I guess? Jason

As long as it's the first commit in mlx5-next, and mlx5-next is 4.20-rc1 based, then pulling this commit into the -rc tree will only pull the single commit. Then when we pull into for-next for the first time, we will get this in for-next too. That seems best to me.
