STPHY(4) BSD Programmer's Manual STPHY(4)NAMESTPHY - Physical layer (PHY) driver on 3C905C ASIC
SYNOPSIS
stphy* at eb? phy ?
DESCRIPTION
The stphy driver supports the PHYceiver built into the 3C905C ASIC for
10baseT and 100baseTX Ethernet. This device driver is called upon by net-
work device drivers; no direct administrative control is provided.
The ifconfig(8) command in conjunction with the device driver making us-
ing of this drivers services provides an administrative interface that
allows various physical level parameters (such as duplex, speed, and
loopback) to be controlled.
The 3C905C supports NWay automatic speed and duplex negotiation as well
as automatic speed detection for hubs that do not support the NWay FLP
protocol (both methods are defined by the IEEE 802.3u standard).
