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” 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 PHY, rev. 1
Supported media types for the PHY can be displayed or set using
the ifconfig(8) media keyword.
