ICS90P(4) BSD Programmer's Manual ICS90P(4)NAME
ICS90P - Physical layer (PHY) driver for ICS 1890 PHYceiver
SYNOPSIS
ics90p* at de? phy ?
DESCRIPTION
The ics90p driver supports the Integrated Circuit Systems 1890 PHYceiver
device (PHY) for 10 and 100 Mb/s Ethernet. This device driver is called
upon by network device drivers; no direct administrative control is pro-
vided.
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 ICS 1890 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).
