The patch titled
PHY probe not working properly for ibm_emac (PPC4xx)

Subject: PHY probe not working properly for ibm_emac (PPC4xx)
From: Hynek Petrak <[EMAIL PROTECTED]>
I have a system with AMCC PowerPC 405EP and PHY Intel LXT971A. Linux
2.6.18.3 is not able to detect the PHY ID correctly. The PHY ID
detected is 0, but should be 0x1d.
This is because phy_read() (__emac_mdio_read() resp.) from
drivers/net/ibm_emac/ibm_emac_core.c might return -ETIMEDOUT or
-EREMOTEIO on error. This is ignored inside the
int mii_phy_probe(struct mii_phy *phy, int address)
from drivers/net/ibm_emac/ibm_emac_phy.c
as the return value is assigned to an u32 variable.
