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.

* enum qca_disconnect_reason_codes - Specifies driver disconnect reason codes.
* Used when the driver triggers the STA to disconnect from the AP.
*
* @QCA_DISCONNECT_REASON_UNSPECIFIED: The host driver triggered the
* disconnection with the AP due to unspecified reasons.
*
* @QCA_DISCONNECT_REASON_INTERNAL_ROAM_FAILURE: The host driver triggered the
* disconnection with the AP due to a roaming failure. This roaming is triggered
* internally (host driver/firmware).
*
* @QCA_DISCONNECT_REASON_EXTERNAL_ROAM_FAILURE: The driver disconnected from
* the AP when the user/external triggered roaming fails.
*
* @QCA_DISCONNECT_REASON_GATEWAY_REACHABILITY_FAILURE: This reason code is used
* by the host driver whenever gateway reachability failure is detected and the
* driver disconnects with AP.
*
* @QCA_DISCONNECT_REASON_UNSUPPORTED_CHANNEL_CSA: The driver disconnected from
* the AP on a channel switch announcement from it with an unsupported channel.
*
* @QCA_DISCONNECT_REASON_OPER_CHANNEL_DISABLED_INDOOR: On a concurrent AP start
* with indoor channels disabled and if the STA is connected on one of these
* disabled channels, the host driver disconnected the STA with this reason
* code.
*
* @QCA_DISCONNECT_REASON_OPER_CHANNEL_USER_DISABLED: Disconnection due to an
* explicit request from the user to disable the current operating channel.
*
* @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
* a timeout for the key installations from the user space.
*
* @QCA_DISCONNECT_REASON_OPER_CHANNEL_BAND_CHANGE: The dDriver disconnected the
* STA on a band change request from the user space to a different band from the
* current operation channel/band.
*
* @QCA_DISCONNECT_REASON_IFACE_DOWN: The STA disconnected from the AP on an
* interface down trigger from the user space.
*
* @QCA_DISCONNECT_REASON_PEER_XRETRY_FAIL: The host driver disconnected the
* STA on getting continuous transmission failures for multiple Data frames.
*
* @QCA_DISCONNECT_REASON_PEER_INACTIVITY: The STA does a keep alive
* notification to the AP by transmitting NULL/G-ARP frames. This disconnection
* represents inactivity from AP on such transmissions.
* @QCA_DISCONNECT_REASON_SA_QUERY_TIMEOUT: This reason code is used on
* disconnection when SA Query times out (AP does not respond to SA Query).
*
* @QCA_DISCONNECT_REASON_BEACON_MISS_FAILURE: The host driver disconnected the
* STA on missing the beacons continuously from the AP.
*
* @QCA_DISCONNECT_REASON_CHANNEL_SWITCH_FAILURE: Disconnection due to STA not
* able to move to the channel mentioned by the AP in CSA.
*
* @QCA_DISCONNECT_REASON_USER_TRIGGERED: User triggered disconnection.
