NAME¶
miibus —
IEEE 802.3 Media Independent
Interface network bus
SYNOPSIS¶
For most network interface cards (NIC):
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.

COMPATIBILITY¶
The implementation of
miibus was originally intended to have
similar API interfaces to
BSD/OS 3.0 and
NetBSD, but as a result are not well behaved newbus
device drivers.
