The only warning that would make sense is if the mixed ports aren't all IB or RoCE. As you note, CX-3 can mix those two, we don't want to see warnings about that.
I would really like to see cx3 be changed to not do that, then we could finalize this issue upstream: All device ports must be the same protocol.
I don't see the point of such artificial limitation, the users who brought CX-3 have option to work in mixed mode and IMHO it is not right to deprecate such ability just because it is hard for us to code for it.
We use cx-3 (& cx-4 & cx-5) in mixed mode all over our RDMA cluster. Loosing that feature is not an option.
