Add a new wowlan_triggers option to wpa_supplicant.conf. The triggers in this key will be used to configure the kernel wowlan configuration. For now, support only simple flags. More complex triggers can be added later on. Signed-off-by: Eliad Peller <eliadx.peller@intel.com>

|
|
* driver operations. This is followed by the struct wpa_driver_ops that each
|
|
* driver wrapper will beed to define with callback functions for requesting
|
|
* driver operations. After this, there are definitions for driver event
|
|
* reporting with wpa_supplicant_event() and some convenience helper functions
|
|
* that can be used to report events.
