DESCRIPTION    [Toc]    [Back]

     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'' autoconfiguration
  attribute.   This  allows  kernel  configuration
files to simply
     specify PHYs as described above in SYNOPSIS.

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

           hme0  at  sbus0 slot 1 offset 0x8c00000 pri 7: address
08:00:20:22:86:b8 rev 34
           nsphy0 at hme0 phy 1: DP83840 10/100 media  interface,
rev. 1

     ifconfig(8) can be used to display the media types supported
by the PHY.
     These media types are valid media keywords for use with  the
ifconfig(8)
     program.
