ray_cs - Raylink wireless LAN - PCMCIA card device driver
is the low level Card Services device driver for the Raylink wireless
LAN PCMCIA adapter. It is normally loaded automatically by card
services according to the parameters specified in
ESS ID - network name to join string with maximum length of 32 chars
default value = "LINUX"
linux standard 16 bit value 1bit/IRQ lsb is IRQ 0, bit 1 is IRQ 1 etc.
Used to restrict choice of IRQ's to use.
0 = adhoc network (default)
1 = infrastructure
(0-5) larger values for more verbose logging.
string of 12 hex digits containing new MAC address.
must be started with x e.g. x00008f123456
hop dwell time in Kilo-microseconds legal values = 16,32,64,128(default),256
Beacon period in Kilo-microseconds.
Legal values = 16,32,64,128,256(default)
must be integer multiple of hop dwell.
Power save mode
0 = continuously active
1 = power save mode (significantly slower)
Power save mode
0 = 802.11 timing
1 = 802.11 modified timing. Interframe spacing is slowed down for
compatibility with older Breezecom access points.
0 = no translation (encapsulate frames)
1 = translation (default)
1 = USA (default)
2 = Europe
3 = Japan
4 = Korea
5 = Spain
6 = France
7 = Israel
8 = Australia
0 = normal network interface - not sniffer (default)
1 = sniffer which can be used to record all network traffic using
tcpdump or similar, but no normal network use is allowed. This is
because linux has no knowledge of 802.11 headers and cannot parse them
correctly. Note that tcpdump does not understand 802.11 headers,
either so it can't interpret the contents, but it can record to a
ray_cs can lock the machine if the card is pulled out while active.
I have never observed a crash if card is deactivated as follows before
The above command assumes that the Raylink card is configured as eth0.
This driver only does encapsulation of ethernet frames within 802.11
frames. Most vendors, including Raytheon, are moving to a frame
translation method. Translation support has been started, but is not
Support for defragmenting frames is not yet tested.
The ioctl support is incomplete. The hardware address cannot be set
using ifconfig yet. If a different hardware address is needed, it may
be set using the phy_addr parameter in ray_cs.opts.
