QS12P(4) BSD Programmer's Manual QS12P(4)NAMEQS12P - Physical layer (PHY) driver
SYNOPSIS
qs12p* at se? phy ?
DESCRIPTION
The qs12p driver supports the Quality Semiconductor PHYceiver device
(PHY) for 10baseT/100baseTX. This device driver is called upon by network
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.
This driver does not support 100baseT4; this can be implemented external-
ly and it is more likely that a separate PHY is used for that.
