BCM52P(4) BSD Programmer's Manual BCM52P(4)NAME
BCM52P - Physical layer (PHY) driver for Broadcomm BCM520x PHYceivers
SYNOPSIS
bcm52p* at eb? phy ?
DESCRIPTION
The bcm52p driver supports the Broadcomm BCM520x series of PHYceivers 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 BCM520x 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).
