hostsleep
This command is used to enable/disable host sleep.
Note: Host sleep parameters should be configured using
"ethtool -s ethX wol X" command before enabling host sleep.
Path: /sys/kernel/debug/libertas_wireless/ethX/
Usage:
cat hostsleep: reads the current hostsleep state
echo "1" > hostsleep : enable host sleep.
echo "0" > hostsleep : disable host sleep
