    wl12xx: fix unsafe dereference of the wlvif

    wlvif could be passed as NULL from the wl1271_tx_work_locked()
    to the wl1271_prepare_tx_frame() and to wl1271_skb_queue_head()
    functions. This may lead to a Kernel panic, fix this by
    validating that wlvif != NULL before using it.

    wl12xx:support ap a2dp coex

    Add functionality to support AP A2DP co-existence:

    1. Add configuration for enable/disable of CTS protection in AP mode
    2. Add indication for completion of connection establishment in ap
       mode. This is used by the firmware to change coex parameters
       when a station is in the process and connecting to the ap and
       change them back after the connection has been established.

    cfg80211: consider security during scan results update

    AP security changes are not updated in the following scenario:
    STA performs a scheduled scan on DFS channel during connection
    to open AP, as some devices (wl12xx) will send a probe req on
    DFS channels once activity is detected, cfg80211 gets and saves
    the scan result from a probe resp. STA disconnected and AP
    security is changed to AES, STA performs a passive scan,
    cfg80211 gets a new scan result for the same BSSID but now from
    beacon. cfg80211_bss_update() finds previous scan result from
    probe resp but the security change is not updated correctly.
    Fix this by considering security mismatch in rb_find_bss.

    wl12xx: FW recovery trigger assert bug fix

    The bug was in the partition mapping. It seems that .mem3 partition that
    we used to write 'magic' 0xCAFECAFE to address 0x1C is actually in use (it
    contains the struct part of the FW_STATUS). It is in use although the size
    of the partition is set to 0

    The fix was to save old partition, map a new partition with .mem part set to
    address 0x1C and remap previous partition after writing 0xCAFECAFE.

    wl12xx: check for required fw change while enable or disable role

    In certain scenarios our current hooks for checking required
    fw change aren't enough and we could be left in MR even though
    we've gone back to a single interface. This is of course not
    good as we prefer running with the SR FW which contains goodies
    like BTCOEX.

    An example scanerio is when running P2P GO + STA and then
    removing the P2P GO.

    Fix it by adding checks for fw change also while enable or
    disable roles.

    wl12xx: decrease elp timeout to 20ms

    The current elp timeout set to 200 ms is too high.
    While its purpose was to avoid going to ELP
    during Tx/Rx the problem is that it keeps the
    device awake also after issuing commands when there's
    no traffic. In Android this is a real problem as
    RSSI is polled by the framework every 3 seconds
    and keeping the chip out of ELP for 200ms each time
    has a significant power consumption effect.

    Fix that by changing to 20ms. This prevents excessive
    real elp sleeps and wakeups during Rx/Tx with 12xx.
    There's no real need any more for setting a hard
    coded 5ms while in forced_ps.

    The fw won't enter elp anyways before the dynamic-ps
    timeout expired as well (and it entered ps
    successfully).

    (Based on a similar patch by Eliad for wlcore)

    wl12xx: triggering FW assert to perform recovery

    Driver based FW recovery was modified. It is now trying to trigger
    FW assert and waiting for WATCHDOG interrupt before continuing with
    recovery.

    This is done to allow FW to perform cleanups and halt gracefully
    before recovery is performed. This allows for safe reading of
    on-demand fwlog, core_dump, etc...

    FW assert triggering is done by writing 0xcafecafe to FW address 0x1c
    and then triggering PHY_RX_HEADER FW interrupt which is its highest
    priority interrupt.

    There is a timeout of 100ms waiting for WATCHDOG interrupt.

    In case timeout is reached or we get ELP or SDIO errors, we resume
    recovery without reading fwlog, core_dump, etc beacuse we assume that
    FW is not responding...

    wl12xx: recovery elp_wakeup optimizations

    We now do several optimizations related to recovery situations:

      We fail elp_wakeup if we have SDIO errors (otherwise we just waste time)

      We now call elp_wakeup inside the recovery work routine to ensure that
      FW is awake for recovery operations (such as ewading core dump, on-
      demand fwlog etc...). This is done prior to disabling wl-interrupts.

      The call to elp_wakeup was removed from userspace recovery trigger routines
      (such as libnl and debugfs) because it is now redundent
