* @NL80211_CMD_RELOAD_REGDB: Request that the regdb firmware file is reloaded.
*
* @NL80211_CMD_EXTERNAL_AUTH: This interface is exclusively defined for host
* drivers that do not define separate commands for authentication and
* association, but rely on user space for the authentication to happen.
* This interface acts both as the event request (driver to user space)
* to trigger the authentication and command response (userspace to
* driver) to indicate the authentication status.
*
* User space uses the %NL80211_CMD_CONNECT command to the host driver to
* trigger a connection. The host driver selects a BSS and further uses
* this interface to offload only the authentication part to the user
* space. Authentication frames are passed between the driver and user
* space through the %NL80211_CMD_FRAME interface. Host driver proceeds
* further with the association after getting successful authentication
* status. User space indicates the authentication status through
* %NL80211_ATTR_STATUS_CODE attribute in %NL80211_CMD_EXTERNAL_AUTH
* command interface.
*
* Host driver reports this status on an authentication failure to the
* user space through the connect result as the user space would have
* initiated the connection through the connect request.
