DP83867 layout question

I would like to swap the polarity on 2 out of the 4 connections between the DP83867 and the magnetics (which have integrated magnetics).  I saw on some threads that linked polarity swapping with mirrored mode.  Does this mean that polarity swapping is not supported in non-mirrored mode?  As well do you need to swap the polarity of all the connections or is it ok to only swap 2 pairs.

    Hi Daniel,

    Mirror mode reorders the channels A->D to D->A but does not change the polarity of those diff pairs. 2 channels cannot be re-ordered.

    Polarity change will be automatically detected and corrected on individual channels as necessary. Polarity correction is independent of channel re-ordering.

    Best Regards,
