Hello, on my notebook, the built in wlan card uses the ipw2100 driver. On boot time, the ipw2100 module is loaded and fires a hotplug "add" event. The hotplug event configures the interface and starts wpa_supplicant and wpa_cli. The ipw2100 chip can be enabled/disabled by a hardware switch, so i only enabled it if i need a connection.
Now: even if the wlan hardware is disabled by the switch, wpa_supplicant tries to get a connection. That's not fine... The ipw2100 driver exports a switch state file in sysfs, but polling this file is not fine also. I want that it works as follows: A state change of the hardware switch should fire a hotplug event, so that the wpa_* programs are started if the switch is put on, and killed if the switch is put off. The ipw2100 driver already logs a state change of the switch in klog, so adding a kobject_uevent should not be the major problem. But which KOBJ_* event enum should be used? KOBJ_ONLINE, KOBJ_OFFLINE ? Or new, user defined, ones? Comments? Suggestions? Thomas "Jetzt Handykosten senken mit klarmobil - 14 Ct./Min.!
