MIIBUS(4) FreeBSD 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: ae(4) Attansic/Atheros L2 Fast Ethernet age(4) Attansic/Atheros L1 Gigabit Ethernet alc(4) Atheros AR8131/AR8132 PCIe Ethernet ale(4) Atheros AR8121/AR8113/AR8114 PCIe Ethernet aue(4) ADMtek USB Ethernet axe(4) ASIX Electronics AX88172 USB Ethernet axge(4) ASIX Electronics AX88178A/AX88179 USB Ethernet bce(4) Broadcom NetXtreme II Gigabit Ethernet bfe(4) Broadcom BCM4401 Ethernet bge(4) Broadcom BCM570xx Gigabit Ethernet cas(4) Sun Cassini/Cassini+ and National Semiconductor DP83065 Saturn dc(4) DEC/Intel 21143 and various workalikes ed(4) NE[12]000, SMC Ultra, 3c503, DS8390 cards et(4) Agere ET1310 Gigabit Ethernet fxp(4) Intel EtherExpress PRO/100B gem(4) Sun ERI, Sun GEM and Apple GMAC Ethernet jme(4) JMicron JMC250 Gigabit/JMC260 Fast Ethernet lge(4) Level 1 LXT1001 NetCellerator Gigabit Ethernet msk(4) Marvell/SysKonnect Yukon II Gigabit Ethernet nfe(4) NVIDIA nForce MCP Networking Adapter nge(4) National Semiconductor DP83820/DP83821 Gigabit Ethernet re(4) RealTek 8139C+/8169/8169S/8110S rl(4) RealTek 8129/8139 rue(4) RealTek RTL8150 USB To Fast Ethernet sge(4) Silicon Integrated Systems SiS190/191 Ethernet sis(4) Silicon Integrated Systems SiS 900/SiS 7016 sk(4) SysKonnect SK-984x and SK-982x Gigabit Ethernet smsc(4) SMSC LAN9xxx USB Fast Ethernet ste(4) Sundance ST201 (D-Link DFE-550TX) stge(4) Sundance/Tamarack TC9021 Gigabit Ethernet udav(4) Davicom DM9601 USB Ethernet ure(4) RealTek RTL8152 USB To Fast Ethernet vge(4) VIA VT612x PCI Gigabit Ethernet vr(4) VIA Rhine, Rhine II vte(4) DM&P Vortex86 RDC R6040 Fast Ethernet 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.
