Introduce QCA_NL80211_VENDOR_SUBCMD_HANG
This is an event indicating to the user space that the driver has detected an internal failure. The driver is expected to recover from such a failure automatically, e.g., by resetting the device. This event carries the information indicating the reason that triggered this detection. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
