What is ASO?
Search yields "Advanced Steering Operation" but that seems Mellanox jargon,
would you mind adding some mlx documentation to describe it? If there are some 
design considerations around it, it may be good to document that too.
Also please provide the long version of the abbreviation in the commit log, at 
least at first usage of it.

And what do you think mentioning from this new support in the release notes?

Thanks,
