13.Os
14.Sh NAME
15.Nm miibus
16.Nd IEEE 802.3 Media Independent Interface network bus
17.Sh SYNOPSIS
18For most network interface cards (NIC):
19.Cd "device miibus"
20.Sh DESCRIPTION
21The
22.Nm
23driver provides an interconnection between the Media Access Control (MAC)
24sublayer, the Physical Layer entities (PHY), Station Management (STA)
25entities, and the PHY Layer as defined by the IEEE 802.3 Standard.
26.Pp
27The
28.Nm
29layer allows network device drivers to share common support
30code for various external PHY devices.
31Most 10/100 network interface cards either use an MII transceiver
32or have built-in transceivers that can be programmed using an MII
33interface.
34The
35.Nm
36driver currently handles all of the media detection,
37selection, and reporting using the ifmedia interface.
38A generic driver has been included for all PHYs that are not
39handled by a specific driver, this is possible because all
4010/100 PHYs implement the same general register set along with
41their vendor specific register set.
42.Pp
43The following network device drivers use the
44.Nm

121.Sh COMPATIBILITY
122The implementation of
123.Nm
124was originally intended to have similar API interfaces
125to
126.Bsx 3.0
127and
128.Nx ,
129but as a result are not well behaved newbus device drivers.
