Sorry, I misinterpreted your previous reply, somehow I thought you
quoted option (3), because my fallible reading of mlx5 was that it
accepts multiple flags.

(First) option 2 is fine.

Do you happen to have a link to what SONiC defined?
We really need to establish some expectations before we start extending
the API. Naively I thought the IEEE spec was more prescriptive :(
