.Nd IEEE 802.3 Media Independent Interface network bus
|
|
|
|
|
.Sh SYNOPSIS
|
|
|
|
|
For most network interface cards (NIC):
|
|
|
|
|
.Cd "device miibus"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides an interconnection between the Media Access Control (MAC)
|
|
|
|
|
sublayer, the Physical Layer entities (PHY), Station Management (STA)
|
|
|
|
|
entities, and the PHY Layer as defined by the IEEE 802.3 Standard.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
layer allows network device drivers to share common support
|
|
|
|
|
code for various external PHY devices.
|
|
|
|
|
Most 10/100 network interface cards either use an MII transceiver
|
|
|
|
|
or have built-in transceivers that can be programmed using an MII
|
|
|
|
|
interface.
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver currently handles all of the media detection,
|
|
|
|
|
selection, and reporting using the ifmedia interface.
|
|
|
|
|
A generic driver has been included for all PHYs that are not
|
|
|
|
|
handled by a specific driver, this is possible because all
|
|
|
|
|
10/100 PHYs implement the same general register set along with
|
|
|
|
|
their vendor specific register set.
|
|
|
|
|
.Pp
|
|
|
|
|
The following network device drivers use the
|
|
|
|
|
.Nm
|

|
|

.Sh COMPATIBILITY
|
|
|
|
|
The implementation of
|
|
|
|
|
.Nm
|
|
|
|
|
was originally intended to have similar API interfaces
|
|
|
|
|
to
|
|
|
|
|
.Bxs 3.0
|
|
|
|
|
and
|
|
|
|
|
.Nx ,
|
|
|
|
|
but as a result are not well behaved newbus device drivers.
