DESCRIPTION

     Media Independent Interface is an IEEE standard serial bus for connecting
     MACs (network controllers) to PHYs (physical media interfaces).  The mii
     layer allows network device drivers to share support code for various PHY
     models, and allows unused support for PHYs which are not present in a
     system to be removed from the kernel.

     Network device drivers which use the mii layer carry the ``mii'' autocon-
     figuration attribute.  This allows kernel configuration files to simply
     specify PHYs as described above in the synopsis.

     The following is an example of the messages displayed when a network
     interface with an attached PHY is detected by the kernel:

           epic0 at pci0 dev 12 function 0: SMC EPIC/100 Fast Ethernet
           epic0: interrupting at kn20aa irq 4
           epic0: SMC9432TX, Ethernet address 00:e0:29:07:17:c4
           qsphy0 at epic0 phy 3: QS6612 10/100 media interface, rev. 1
           qsphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

     All PHY drivers display the media types supported by the PHY when it is
     detected by the kernel.  These media types are valid media keywords for
     use with the ifconfig(8) program.
