68 Media Independent Interface is an IEEE standard serial bus for
69 connecting MACs (network controllers) to PHYs (physical media
72 layer allows network device drivers to share support code for
73 various PHY models, and allows unused support for PHYs which
74 are not present in a system to be removed from the kernel.
76 Network device drivers which use the
80 autoconfiguration attribute. This allows kernel configuration
81 files to simply specify PHYs as described above in the synopsis.
83 The following is an example of the messages displayed when a network
84 interface with an attached PHY is detected by the kernel:
85 .Bd -literal -offset indent
86 epic0 at pci0 dev 12 function 0: SMC EPIC/100 Fast Ethernet
87 epic0: interrupting at kn20aa irq 4

90 qsphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
93 All PHY drivers display the media types supported by the PHY when it
94 is detected by the kernel. These media types are valid media keywords
