# Wireless LAN adapter configuration
#
# Theory of operation : 
#
# The script attempts to match a block of settings to the specific wireless
# card inserted, the *first* block matching the card is used.
# The address format is "hwaddr", with * as a wildcard.
# 'hwaddr' is the unique MAC address identifier of the wireless card.
# The MAC address is usually printed on the card, or can be found via ifconfig.
# Some examples here use only half of the MAC address with a wildcard to
# match a whole family of cards...
#
# All the Wireless specific configuration is done through the Wireless
# Extensions, so we will just call 'iwconfig' with the right parameters
# defined below.
# Of course, you need to have iwconfig installled on your system.
# To download iwconfig, or for more info on Wireless Extensions :
#	http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
#
# Note : you don't need to fill all parameters, leave them blank, in most
# cases the driver will initialise itself with sane defaults values or
# automatically figure out the value... And no drivers do support all
# possible settings...
#
# -- This is a modified '/etc/pcmcia/wireless.opts' script --
# -- I added sections for Prism/GT and Atheros based cards --
# --    (supported by the prism54 and madwifi drivers)     --
