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.
I don't really think it is really too user visible.. Only the device
and port number change, but only if running in mixed mode.
Ahh, correct me if I'm wrong, you are proposing to split mlx4_ib devices
to two devices once it is configured in mixed mode, so everyone will
have one port only. Did I understand you correctly?
Which would require splitting resources that are shared now? other splitting issue(s)?
It is not just 'hard for us' it is impossible to reconcile the
differences between ports when enforcing device level things.
This keeps coming up again and again..
