adapter (and some workalikes). Also add man pages and a wicontrol utility to manipulate some of the card parameters. This driver was written using information gleaned from the Lucent HCF Light library, though it does not use any of the HCF Light code itself, mainly because it's contaminated by the GPL (but also because it's pretty gross). The HCF Light lacks certain featurs from the full (but proprietary) HCF library, including 802.11 frame encapsulation support, however it has just enough register information about the Hermes chip to allow someone with enough spare time and energy to implement a proper driver. (I would have prefered getting my hands on the Hermes manual, but that's proprietary too. For those who are wondering, the Linux driver uses the proprietary HCF library, but it's provided in object code form only.) Note that I do not have access to a WavePOINT access point, so I have only been able to test ad-hoc mode. The wicontrol utility can turn on BSS mode, but I don't know for certain that the NIC will associate with an access point correctly. Testers are encouraged to send their results to me so that I can find out if I screwed up or not.

Lucent Technologies WaveLAN/IEEE 802.11 PCMCIA driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device wi0 at isa? port? net irq?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for WaveLAN/IEEE PCCARD adapters (also known
|
|
as WaveLAN II cards). Note that while Lucent sells both ISA and PCMCIA
|
|
WaveLAN/IEEE devices, the ISA product is actually a PCMCIA card in an
|
|
ISA to PCMCIA bridge adapter. The
|
|
.Nm
|
|
driver supports both the ISA and PCMCIA devices.
|
|
.Pp
|
|
The core of the WaveLAN/IEEE is the Lucent Hermes controller. All
|
|
host/device interaction is via programmed I/O with the Hermes. The
|
|
Hermes supports 802.11 and 802.3 frames, power management, BSS, WDS
|
|
and ad-hoc operation modes. The
|
|
.Nm
|
|
driver encapsulates all IP and ARP traffic as 802.11 frames, however
|
|
it can receive either 802.11 or 802.3 frames. Transmit speed is
|
|
selectable between 1Mbps fixed, 2Mbps fixed or 2Mbps with auto fallback.
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the WaveLAN card for ad-hoc operation. In this mode,
|
|
stations can communicate among each other without the aid of an access
|
|
point. To join a service set, the driver must be set for BSS mode using
|
|
the
|
|
.Xr wicontrol 8
|
|
utility.
|
|
.Pp
|
|

|
|
.Xr ifconfig 8

|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "wi%d: init failed"
|
|
The WaveLAN failed to come ready after an initialization command was
|
|
issued.
|
|
.It "wi%d: failed to allocate %d bytes on NIC"
|
|
The driver was unable to allocate memory for transmit frames in the
|
|
NIC's on-board RAM.
|
|
.It "wd%d: device timeout"
|
|
The WaveLAN failed to generate an interrupt to acknowledge a transmit
|
|
command.
