DP83825I: Manual 100Mbps setup fails on DP83825I.

Part Number: DP83825I

I have confirmed that the below sequence works.

auto-negotiation (100mbps full) -> manual 100Mbps(full or half)
auto-negotiation (100mbps full) -> manual 10Mbps(full or half)
manual 100Mbps(full or half) -> auto-negotiation (100mbps full)
manual 10Mbps(full or half) -> auto-negotiation (100mbps full)
manual 100Mbps(full or half) -> manual 10Mbps(full or half)

But it always fails in the case below.

manual 10Mbps(full or half) -> manual 100Mbps(full or half)

The register values are as follows.

Write
- BMCR:0x2100

Read
- BMSR: 0x7849
- PHYSTS: 0x1104 or 0x5104
