Introduce QCA_NL80211_VENDOR_SUBCMD_DRIVER_DISCONNECT_REASON
This acts as an event from the host driver to the user space to notify the driver specific reason for a disconnection. The host driver initiates the disconnection for various scenarios (beacon miss, Tx Failures, gateway unreachability, etc.) and the reason codes from cfg80211_disconnected() do not carry these driver specific reason codes. Host drivers should trigger this event immediately prior to triggering cfg80211_disconnected() to allow the user space to correlate the driver specific reason code with the disconnect indication.

* @QCA_DISCONNECT_REASON_GATEWAY_REACHABILITY_FAILURE: This reason code is used

*
|

* @QCA_DISCONNECT_REASON_UNSUPPORTED_CHANNEL_CSA: The driver disconnected from

*
|

* @QCA_DISCONNECT_REASON_OPER_CHANNEL_DISABLED_INDOOR: On a concurrent AP start

* disabled channels, the host driver disconnected the STA with this reason
|

* code.
|

* @QCA_DISCONNECT_REASON_OPER_CHANNEL_USER_DISABLED: Disconnection due to an

|

*
|

* @QCA_DISCONNECT_REASON_DEVICE_RECOVERY: STA disconnected from the AP due to

* the internal host driver/firmware recovery.
|

*
|

* @QCA_DISCONNECT_REASON_KEY_TIMEOUT: The driver triggered the disconnection on

*
|

* @QCA_DISCONNECT_REASON_OPER_CHANNEL_BAND_CHANGE: The dDriver disconnected the

*
|

* @QCA_DISCONNECT_REASON_PEER_INACTIVITY: The STA does a keep alive
|

* represents inactivity from AP on such transmissions.
|

|
||||

|
