LU12P(4) BSD Programmer's Manual LU12P(4)NAME
LU12P - Physical layer (PHY) driver for Lucent 6612 PHY
SYNOPSIS
lu12p* at hme? phy ?
DESCRIPTION
The lu12p driver supports the Lucent 6612 PHY for 10 and 100 Mb/s Ether-
net. This design is also used as '1612' chip in SPARC hardware. This
device driver is called upon by network device drivers; no direct admin-
istrative 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 LU6612 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).
