SYNOPSIS

For most network interface cards (NIC):
.Cd "device miibus"

DESCRIPTION

The miibus 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.

The miibus 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 miibus 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.

The following network device drivers use the miibus interface:

COMPATIBILITY

The implementation of miibus was originally intended to have similar API interfaces to
.Bsx 3.0 and
.Nx , but as a result are not well behaved newbus device drivers.
