MIIBUS(4)             DragonFly 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 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(4) 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: ae(4) Attansic/Atheros L2 FastEthernet age(4) Attansic/Atheros L1 Gigabit Ethernet alc(4) Atheros AR8131/AR8132 Gigabit/Fast Ethernet ale(4) Atheros AR8121/AR8113/AR8114 Gigabit/Fast Ethernet aue(4) ADMtek USB Ethernet axe(4) ASIX Electronics AX88172 USB Ethernet axge(4) ASIX Electronics AX88178A/AX88179 USB Gigabit Ethernet bce(4) Broadcom BCM5706/BCM5708 Gigabit Ethernet bfe(4) Broadcom BCM440x 10/100 Ethernet bge(4) Broadcom BCM570xx Gigabit Ethernet dc(4) DEC/Intel 21143 and various workalikes et(4) Agere ET1310 10/100/1000 Ethernet fxp(4) Intel EtherExpress PRO/100B jme(4) JMicron Gigabit Ethernet lge(4) Level 1 LXT1001 NetCellerator Gigabit Ethernet mos(4) Moschip MCS7730/MCS7830/MCS7832 USB Ethernet msk(4) Marvell/SysKonnect Yukon II Gigabit Ethernet nfe(4) NVIDIA nForce MCP 10/100/Gigabit Ethernet 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 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) stge(4) Sundance/Tamarack TC9021 Gigabit Ethernet tl(4) Texas Instruments ThunderLAN tx(4) SMC EtherPower II (83c170) udav(4) Davicom DM9601 USB Ethernet vge(4) VIA Networking Technologies VT6122 PCI Gigabit 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.
