.Sh NAME
|

.Nm ray
|
|
.Nd Raytheon Raylink/Webgear Aviator PCCard driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device ray"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for
|
|
.Tn "Raytheon Raylink"
|
|
adapters (commonly available as
|
|
.Tn "Webgear Aviator" ,
|
|
.Tn "Webgear Aviator Pro"
|
|
and
|
|
.Tn "Raylink PC Card"
|
|
devices.)
|
|
The core of the
|
|
.Tn Raylink
|
|
cards is a frequency hopping PHY with an
|
|
.Tn IEEE
|
|
802.11
|
|
style MAC that interacts with the host using shared memory and mailboxes.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver currently supports ad-hoc operation mode and the
|
|
.Tn Aviator
|
|
cards.
|
|
Infrastructure mode, interworking with
|
|
.Tn "Windows 2000" Ns / Ns Tn Linux Ns / Ns Nx ,
|
|
.Tn "Raylink PC Cards"
|
|
and
|
|
.Tn "Aviator Pros"
|
|
is rudimentary and in active development.
|
|
The
|
|
.Nm
|
|
driver currently encapsulates all IP and ARP traffic as
|
|
.Tn Ethernet
|
|
2 frames within an
|
|
.Tn IEEE
|
|
802.11
|
|
frame.
|
|
Other translations will be forthcoming as needed.
|
|
Transmit speed is
|
|
selectable between 0.5Mbps, 1Mbp , 1.5Mbps or 2Mbps all with auto fallback.
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the card for ad-hoc operation.
|
|
In this mode,
|
|
stations can communicate amongst each other without the aid of an access
|
|
point.
|
|
To join a managed service set, the driver must be set for infrastructure mode
|
|
using the
|
|
.Xr raycontrol 8
|
|
utility.
|
|
.Pp
|
|
There are two known firmware versions; version 4 and version 5.
|
|
Version 4 firmware was shipped on the orignal
|
|
.Tn "Webgear Aviators"
|
|
Version 5 firmware is
|
|
used as part of the
|
|
.Tn "Windows 2000"
|
|
upgrade from
|
|
.Tn Webgear
|
|
and on the
|
|
.Tn "Aviator Pro" ,
|
|
and
|
|
.Tn "Raylink PC Cards"
|
|
cards.
|
|
Version 4 is not likely to be 100%
|
|
.Tn IEEE
|
|
802.11
|
|
compliant - version 5 should be.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8
|
|
and
|
|
.Xr raycontrol 8 .
|
|
.Sh DIAGNOSTICS
|
|
The following messages occur when there are problems
|
|
setting up the memory mapped buffers due to nits in
|
|
.Xr pccardd 8 .
|
|
.Bl -diag
|
|
.It "ray?: pccardd did not map CM - giving up"
|
|
See the
|
|
.Sx BUGS
|
|
section and contact the author for help enclosing a copy
|
|
of the output from
|
|
.Xr dmesg 8 .
|
|
This message only occurs on 3.x systems.
|
|
.It "ray?: fixing up CM ..."
|
|
.It "ray?: fixing up AM ..."
|
|
The driver is fixing up PCCard memory management after mis-configuration
|
|
by
|
|
.Xr pccardd 8 ,
|
|
benign.
|
|
.El
|
|
.Pp
|
|
.Bl -diag
|
|
On 4.x and -current systems the following messages can occur when the
|
|
memory mapped buffers are set up.
|
|
.It "ray?: allocated common memory:"
|
|
.It ". start 0xd0000 count 0xc0000 flags 0x40"
|
|
Benign.
|
|
.It "ray?: allocated attribute memory:"
|
|
.It ". start 0xdc000 count 0x1000 flags 0x50"
|
|
Benign.
|
|
.It "ray?: allocated irq:"
|
|
.It ". start 0x9 count 0x1"
|
|
Benign.
|
|
.It "ray?: Cannot allocate attribute memory"
|
|
.It "ray?: Cannot allocate common memory"
|
|
.It "ray?: Cannot allocate irq"
|
|
.It "ray?: Failed to setup irq"
|
|
.It "ray?: CARD_SET_MEMORY_OFFSET returned 0x??"
|
|
.It "ray?: CARD_SET_RES_FLAGS returned 0x??"
|

.Pp

.Bl -diag
|
|
If the kernel is booted with the verbose flag turned on then the
|
|
extra information is printed when the driver is probed.
|
|
These messages are also seen when the
|
|
.Dv RAY_DBG_BOOTPARAM
|
|
bit in the
|
|
.Dv RAY_DEBUG
|
|
option is turned on, as is the case for all existing
|
|
versions of the driver.
|
|
.It "ray?: memory start 0x???? count 0x???? flags 0x???? offset 0x????"
|
|
Description of memory map settings on entry to the driver.
|
|
.It "ray?: irq start 0x???? count 0x????"
|
|
Description of irq settings on entry to the driver (only on 4.1 and
|
|
above).
|
|
.El
|
|
.Pp
|
|
On start-up the driver will report hardware failures thus:
|
|
.Bl -diag
|
|
.It "ray?: card failed self test: status 0x??<???>"
|
|
The card failed to come ready after it was plugged in to the PCCard
|
|
slot.
|
|
The most common cause of this message is incorrect PCCard memory
|
|
management (indicated by a status of 0xff or 0x55).
|
|
Bent cards might say that the receiver calibration failed.
|
|
If you are brave enough removing the
|
|
base of the case can resurrect cards (no warranties etc.).
|
|
.It "ray?: unsupported firmware version 0x??"
|
|
Self explanatory.

|
|
option of

.Xr ifconfig 8 .
|
|
.Bl -diag
|
|
.It "ray?: cannot transmit - not running"
|
|
A packet was ready for transmission but the NIC is not connected to a
|
|
BSS.
|
|
May occur when removing the PCCard.
|
|
.It "ray?: cannot transmit - no network"
|
|
The wireless NIC has roamed from an access point and not connected with a new
|
|
one yet.
|
|
.It "ray?: cannot transmit - ECF busy"
|
|
The controller firmware was busy when a packet was about to be sent out.
|
|
It will be retried automatically.
|
|
.It "ray?: mbuf too long ??"
|
|
Should never happen, and if it does represents something wrong in the
|
|
generic Ethernet driver in the kernel.
|
|
.It "ray?: could not pullup ether"
|
|
Problem with re-aligning mbufs.
|
|
Very unlikely to happen.

|
An impossible error - mail the author.
|
|
.It "ray?: could not translate packet"
|
|
An error occurred when trying to re-frame a packet for transmission.

|
.It "ray?: tx completed but status is fail"
|
|

|
|
.It "ray?: packet too big or too small"
|
|
A received packet was impossibly small or too large to fit into an mbuf.
|
|
.It "ray?: MGETHDR failed"
|
|
The driver could not get a mbuf to store a received packet into.
|
|
Try increasing
|
|
.Dv MAXUSERS
|
|
in your kernel configuration.
|
|
.It "ray?: MCLGET failed"
|
|
The driver could not get a mbuf to store a received packet into.

|
|
The lengths of a fragmented packet were inconsistent.

|
|
The received
|
|
.Tn IEEE
|
|

|
|
The NIC has generated an interrupt signalling that

|
processing of a packet that is only ever used in Japanese RCR
|
|
certification tests.
|
|
Represents firmware/hardware/driver bugs unless you
|
|
are trying to certify the NICs in Japan (in which case you would have to
|
|
of modified the driver and this manual is out of date).
|

.It "ray?: spinning"
|
|
The controller firmware was busy when a command was about to be issued.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 3.3 .
|
|
.Sh AUTHORS
|
|
.An -nosplit
|
|
Early versions of this
|
|
.Nm
|
|
driver were a port of the
|
|
.Nx
|
|
driver by
|
|
.An "Christian E. Hopps" .
|
|
The driver
|
|
was re-structured by
|
|
.An Duncan Barclay Aq dmlb@FreeBSD.org ,
|
|
so that
|
|
.Xr dhclient 8
|
|
would work.
|
|
.Sh BUGS
|
|
Infra-structure mode is not supported yet.
|
|
The driver is likely to panic if it is set into this mode.
|
|
Testers are encouraged to contact the
|
|
author.
|
|
.Pp
|
|
Currently
|
|
.Fx
|
|
has a small problem managing and setting up the correct memory maps.
|
|
However, this driver should reset the
|
|
memory maps correctly - it works around
|
|
.Xr pccardd 8
|
|
(where it reads the CIS for common memory, sets it all up
|
|
and then throws it all away assuming the card is an
|
|
.Xr ed 4
|
|
driver...).
|
|
Note that this could be dangerous (because it does not interact with
|
|
.Xr pccardd 8 )
|
|
if you use other memory mapped cards at the same time or have
|
|
SCSI cards with on-board BIOS.
|
|
.Pp
|
|
More encapsulations and translations could be supported, but they have
|
|
little value unless someone can demonstrate that the
|
|
.Nm
|
|
cards will communicate with other manufacturers cards.
|
|
Version 4 and
|
|
firmware is not
|
|
.Tn IEEE
|
|
802.11
|
|
compliant, but version 5 is.
|
|
.Pp
|
|
To communicate with
|
|
.Tn Windows
|
|
machines ensure that the
|
|
.Tn Windows
|
|
machine
|
|
creates the BSS/IBSS.
|
|
.Pp
|
|
The driver currently panics on some errors that it should recover from.
|
|
These will be removed RSN.
