Log Message:
QEMU e1000's PHY code doesn't implement register 16. Do workaround.
- Marvell 88E1[01]11 (and many other Marvell PHYs) have the Fiber/Copper
auto selection feature. Our makphy(4) implement it but QEMU doesn't.
If it fails, a garbage data is used in the attach function and unexpected
media may be used. Fix this behavior by checking the return value of
PHY_READ(MAKPHY_ESSR). If the access failed, the media is regarded
as copper only. It's just a cosmetic change. It's not affected to the
packet processing.
