MIIBUS(4) BSD Kernel Interfaces Manual MIIBUS(4) 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 Man- agement (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 spe- cific register set. The following network device drivers use the miibus interface: aue(4) ADMtek USB Ethernet axe(4) ASIX Electronics AX88172 USB Ethernet bfe(4) Broadcom BCM4401 Ethernet bge(4) Broadcom BCM570xx Gigabit Ethernet dc(4) DEC/Intel 21143 and various workalikes ed(4) NE[12]000, SMC Ultra, 3c503, DS8390 cards fxp(4) Intel EtherExpress PRO/100B gem(4) Sun ERI, Sun GEM and Apple GMAC Ethernet gx(4) Intel Pro/1000 82542/82543 Gigabit Ethernet hme(4) Sun HME Ethernet lge(4) Level 1 LXT1001 NetCellerator Gigabit Ethernet my(4) Myson Technologies PCI Ethernet adaptors nge(4) National Semiconductor DP83820/DP83821 Gigabit Ethernet pcn(4) AMD Am79C97x PCI 10/100 re(4) RealTek 8139C+/8169/8169S/8110S rl(4) RealTek 8129/8139 rue(4) RealTek RTL8150 USB To Fast Ethernet sf(4) Adaptec AIC-6915 sis(4) Silicon Integrated Systems SiS 900/SiS 7016 sk(4) SysKonnect SK-984x and SK-982x Gigabit Ethernet ste(4) Sundance ST201 (D-Link DFE-550TX) tl(4) Texas Instruments ThunderLAN tx(4) SMC EtherPower II (83c170) udav(4) Davicom DM9601 USB Ethernet vr(4) VIA Rhine, Rhine II wb(4) Winbond W89C840F xl(4) 3Com 3c90x 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.
