* p80211netdev_hwremoved
*
* Hardware removed notification. This function should be called
* immediately after an MSD has detected that the underlying hardware
* has been yanked out from under us.  The primary things we need
* to do are:
*   - Mark the wlandev
*   - Prevent any further traffic from the knetdev i/f
*   - Prevent any further requests from mgmt i/f
*   - If there are any waitq'd mgmt requests or mgmt-frame exchanges,
*     shut them down.
*   - Call the MSD hwremoved function.
*
* The remainder of the cleanup will be handled by unregister().
* Our primary goal here is to prevent as much tickling of the MSD
* as possible since the MSD is already in a 'wounded' state.
*
* TODO: As new features are added, this function should be
*       updated.
*
* Arguments:
*	wlandev		WLAN network device structure
* Returns:
*	nothing
* Side effects:
*
* Call context:
*	Usually interrupt.
