* [PATCH] phy address mask support for generic phy layerMatt Porter2005-11-051-0/+3
| | | | | | | | | | | | | | Adds a phy_mask field to struct mii_bus and uses it. This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask.

* [PATCH] PHY Layer fixupAndy Fleming2005-08-281-0/+17
| | | | | | | | | | | | | | This patch adds back the code that was taken out, thus re-enabling: * The PHY Layer to initialize without crashing * Drivers to actually connect to PHYs * The entire PHY Control Layer This patch is used by the gianfar driver, and other drivers which are in development.
