# xircnw\_cs(4)

Xircom Creditcard Netwave device driver

## NAME

xircnw\_cs - Xircom Creditcard Netwave device driver

## SYNOPSIS

**insmod xircnw\_cs.o** \[**pc\_debug=n**\] \[**domain=n**\] \[**scramble\_key=n**\] \[**mem\_speed=n**\] \[**irq\_mask=n**\]

## DESCRIPTION

**Xircnw\_cs** is the low-level Card Services driver for the Xircom Creditcard Netwave PCMCIA wireless network adapter.  When this driver is attached to a card, it allocates the next available ethernet device (**eth0**..**eth#**). This device name will be reported in the kernel log file, and will be passed on to [**cardmgr**(8)](/cardmgr/8.md).

The wireless domain number and scrambling key can be specified using module parameters when the module is loaded.  These parameters should be specified in */etc/pcmcia/config.opts*.

## PARAMETERS

- **pc\_debug=n**

  Selects the PCMCIA debugging level.  This parameter is only available if the module is compiled with debugging enabled.  A non-zero value enables debugging.

- **domain=n**

  Selects what access point(s) to talk to, by their domain number. Values from 0 to 0x1ff are valid; 0x100 is the default.

- **scramble\_key=n**

  Selects the scramble key for domains that are scrambled.  Values from 0 to 0x1ff are valid.  The default is 0 (no scrambling).

- **mem\_speed=n**

  Sets the access speed of the shared memory window, in nanoseconds. The default is 0 (i.e., no extra wait states).  Values of up to 1000 are legal.

- **irq\_mask=n**

  Specifies the set of interrupts that may be allocated by this driver. Each bit of the mask word corresponds to one irq number: 0x0001 is irq 0, 0x0002 is irq 1, etc.

## BUGS

The statistics reported back from the driver are wrong.
