Oh, so here's the issue, we have both PHY variants, older hardware
generally has AC200 PHY's while newer ships AC300 PHY's, but
when I surveyed our deployed hardware using these boards many
systems of similar age would randomly mix AC200 and AC300 PHY's.

It appears there was a fairly long transition period where both variants
were being shipped.
