config

和我之前上载的intel 802.11协议源码是配套的

	echo "No '${ENTRY}' found in /sys/bus/pci/drivers/${MODULE}."

	VAL=1
	for ((i = 0; i < $2; i++)); do
		VAL=$((VAL*2))

	SET="$((VAL & $3))"
	if [ "${SET}" = "0" ]; then
		SET=" "

	fi
	printf "%-20s\t\t0x%08X [%s] %d\n" $1 $VAL "$SET" $i
}

IFS="

LEVELS=`sed -ne "${EREG}" ipw2200.h`
VALUE=`cat ${FILE}`

printf "%-20s\t\t%-10s Set Bit\n" "Description" "Hex"
for i in $LEVELS; do
	IFS="

	bit $i $((${VALUE}))
done

printf "${ENTRY} = ${VALUE} (* = active)\n"
