|
.Sh DESCRIPTION
|
|
The
|
|
.Nm tl
|
|
device driver supports network adapters based on
|
|
the Texas Instruments ThunderLAN chip on i386 CPUs.
|
|
Supported cards include:
|
|
.Pp
|
|
.Bl -tag -width xxxxxx -offset indent
|
|
.It Compaq Netelligent
|
|
in baseboard and PCI variants (10bT-only and dual-port variants untested).
|
|
.It Compaq NetFlex 3/P
|
|
in baseboard and PCI variants (only baseboard variant tested).
|
|
.It Baseboard Compaq Deskpro 4000 5233MMX ethernet (untested).
|
|
.El
|
|
|
|
.Sh MEDIA SELECTION
|
|
The different models of the supported boards come with some subset of RJ-45,
|
|
BNC and AUI connectors. Supported media include:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxx -offset indent
|
|
.It AUI/DIX
|
|
Standard 15 pin connector
|
|
.It 10Base2
|
|
BNC, also known as thin-net
|
|
.It 10BaseT
|
|
UTP, also known as twisted pair
|
|
.It 100baseTX
|
|
100Mbit over cat-5 UTP
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver don't have automatic media selection, and there is no media selected
|
|
by default. An explicit medium must be specified to
|
|
.Xr ifconfig 8
|
|
or in your /etc/ifconfig.tl? file. The media option
|
|
.Em full-duplex
|
|
can be used to switch the UTP port in full-duplex mode.
|
|
|
|
.Sh DIAGNOSTICS
|
|
.Dl "tl0: no carrier"
|
|
.Dl "nsphy0: 10baseT: no carrier"
|
|
.in +4
|
|
means that the driver detected a carrier loss. This usually indicates a bad
|
|
link.
|
|
.in -4
|
|
.Sh BUGS
|
|
.Pp
|
|
The board marked as untested will always claim having an AUI connector, where
|
|
it may be a BNC one.
|
|
.Pp
|
|
The driver really should have a media autosensing function.
|
|
.Pp
|
|
On AUI and BNC ports, false carrier loss may be detected on heavily-loaded
|
|
networks.
