Public bug reported:
Binary package hint: laptop-mode-tools
In all the three modules:
$IWCONFIG $IFNAME >/dev/null 2>&1;
ret=$?;
if [ "$ret" = "0" ]; then
# Yes, it is a wireless device.
....
However, iwconfig gleefully returns status code 0 for any network
device. This results in ugly error messages afterwards.
Moreover, in wireless-power:
if ( ! iwconfig $IF power $WIRELESS_AC_POWER_SAVING_ONOFF ) ; then
if ( ! iwconfig $IF power $WIRELESS_BATT_POWER_SAVING_ONOFF ) ; then
Not using the $IWCONFIG variable defined earlier.
Moreover, wireless-power supports WIRELESS_POWER_SAVING_EXCLUDE_DRIVERS,
whereas wireless-{iwl,ipw}-power do not.
Moreover,
# LP: #369113
# Kernel's 2.6.29 and above have been reported to be missing
# the $DEVICE/wireless folder.
See the OCNFIG_WIRELESS_EXT_SYSFS kernel variable for that.
** Affects: laptop-mode-tools (Ubuntu)
Importance: Undecided
Status: New
