The early Intel cards without integrated PHY often used Marvell PHYs.
Many if not most of the Intel PHYs are derived from the separate Marvell
PHYs and some of the early integrated ones even claim to be made by
Since em(4) doesn't use the generic MII/PHY framework there will have been
no testing of eephy for these cases on OpenBSD. It probably wants some,
lest we break wm(4) by replacing makphy.
