The Linux drivers for Texas Instruments' Ethernet physical layer (PHY) transceivers support communication through the serial management interface (MDC/MDIO) to configure and read PHY registers.
The USB-2-MDIO software lets you directly access the registers during debug and prototyping. This tool supports all TI Ethernet PHYs.
Enabling driver support
Configure kernel with "make menuconfig" (alternatively use "make xconfig" or "make nconfig")
