They say they have no plan to fix this ERRATA in future releases.

The errata applies to specific revisions, is this revision present in
the lower 4 bits of the MII_PHYSID2 register such that it could be used
to key the disabling of the power down?

It doesn't appear that KSZ9031 is affected by this errata; no mention of suspend:
