fc99dd0829 mwifiex: do not process broadcast mac address for del_sta
Generally broadcast mac address deauth is followed by stop_ap or start_ap.
In both cases, FW already has provision to send deauth; so there is no
need to handle broadcast mac deauthentication.

c11fb9857f mwifiex: guard station nodes access by station list lock
Station node entries should be guarded for whole of their reference
instead of just while getting node entry from station list.
It may happen that station node is retrieved may be deleted by
deauthentication event while it is still in use.

dda9ddeb26 mwifiex: do not delete station entries in del_sta handler
A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.

This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

2f010b5588 Bluetooth: Add support for handling LE Direct Advertising Report events
When the controller sends a LE Direct Advertising Report event, the host
must confirm that the resolvable random address provided matches with
its own identity resolving key. If it does, then that advertising report
needs to be processed. If it does not match, the report needs to be
ignored.

This patch adds full support for handling these new reports and using
them for device discovery and connection handling. This means when a
Bluetooth controller supports the Extended Scanner Filter Policies, it
is possible to use directed advertising with LE privacy.

1b9b5ee530 Bluetooth: Add callback to create proper cmd_complete events
We've got a couple of generic scenarios where all pending mgmt commands
are processed and responses are sent to them. These scenarios are
powering off the adapter and removing the adapter. So far the code has
been generating cmd_status responses with NOT_POWERED and INVALID_INDEX
resposes respectively, but this violates the mgmt specification for
commands that should always generate a cmd_complete.

This patch adds support for specifying a callback for the pending_cmd
context that each command handler can use for command-specific
cmd_complete event generation. The actual per-command event generators
will come in subsequent patches.

5580373fb2 SSB / B44: fix WOL for BCM4401
Wake On Lan was not working on laptop DELL Vostro 1500.
If WOL was turned on, BCM4401 was powered up in suspend mode. LEDs blinked.
But the laptop could not be woken up with the Magic Packet. The reason for
that was that PCIE was not enabled as a system wakeup source and
therefore the host PCI bridge was not powered up in suspend mode.
PCIE was not enabled in suspend by PM because no child devices were
registered as wakeup source during suspend process.
On laptop BCM4401 is connected through the SSB bus, that is connected to the
PCI-Express bus. SSB and B44 did not use standard PM wakeup functions
and did not forward wakeup settings to their parents.
To fix that B44 driver enables PM wakeup and registers new wakeup source
using device_set_wakeup_enable(). Wakeup is automatically reported to the parent SSB
bus via power.wakeup_path. SSB bus enables wakeup for the parent PCI bridge, if there is any
child devices with enabled wakeup functionality. All other steps are
done by PM core code.
