|
|
.Sh SYNOPSIS
|
|
.Cd "device miibus"
|
|
.Cd "device tl"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for PCI ethernet adapters based on the Texas
|
|
Instruments ThunderLAN ethernet controller chip.
|
|
This includes a large
|
|
number of Compaq PCI-bus ethernet adapters as well as the integrated
|
|
ethernet controllers built in to several models of Compaq Prosignia
|
|
servers and Compaq Deskpro desktop machines.
|
|
This driver also supports
|
|
the Olicom OC-2135/2138, OC-2325 and OC-2326 10/100 TX UTP adapters
|
|
and the Racore 8165 10/100baseTX and 8148 10baseT/100baseTX/100baseFX
|
|
multi-personality cards.
|
|
.Pp
|
|
The ThunderLAN controller has a standard MII interface that supports
|
|
up to 32 physical interface devices (PHYs). It also has a built-in
|
|
10baseT PHY hardwired at MII address 31, which may be used in some
|
|
10Mbps-only hardware configurations.
|
|
In 100Mbps configurations, a
|
|
National Semiconductor DP83840A or other MII-compliant PHY may be
|
|
attached to the ThunderLAN's MII bus.
|
|
If a DP83840A or equivalent
|
|
is available, the ThunderLAN chip can operate at either 100Mbps or
|
|
10Mbps in either half-duplex or full-duplex modes.
|
|
The ThunderLAN's
|
|
built-in PHY and the DP83840A also support autonegotiation.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It autoselect
|
|
Enable autoselection of the media type and options.
|
|
Note that this
|
|
option is only available on those PHYs that support autonegotiation.
|
|
Also, the PHY will not advertise those modes that have been explicitly
|
|
disabled using the following media options.
|
|
.It 10baseT/UTP
|
|
Set 10Mbps operation
|
|
.It 100baseTX
|
|
Set 100Mbps (fast ethernet) operation
|
|
.It 10base5/AUI
|
|
Enable AUI/BNC interface (useful only with the built-in PHY).
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It full-duplex
|
|
Force full duplex operation
|
|
.It half-duplex
|
|
Force half duplex operation.
|
|
.It hw-loopback
|
|
Enable hardware loopback mode.
|
|
.El
|
|
.Pp
|
|
Note that the 100baseTX media type is only available if supported
|
|
by the PHY.

.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "tl%d: couldn't map memory"
|
|
A fatal initialization error has occurred.
|
|
.It "tl%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "tl%d: device timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
|
|
.It "tl%d: no memory for rx list"
|
|
The driver failed to allocate an mbuf for the receiver ring.
|
|
.It "tl%d: no memory for tx list"
|
|
The driver failed to allocate an mbuf for the transmitter ring when
|
|
allocating a pad buffer or collapsing an mbuf chain into a cluster.
