AR9382 needs to be configured for the correct chain mask before
running AGC/TxIQ caliberation. Otherwise reset would fail.

Support setting the antenna configuration via cfg/mac80211. At the moment only
allow the simple pre-defined configurations we already have (fixed antenna A/B
or diversity), but more advanced settings are possible to implement.

BCM4320a devices seem to sometimes do scanning pretty poorly. This can be
workaround by issuing new scan every second, while not yet connected. By this
new scanning method device catches beacons much faster. Fixes bug #20822.

BCM4320a devices do not return bss for currently connected AP in bss-list,
althought this is required by NDIS specs. Missing bss leads to warning at
net/wireless/sme.c:__cfg80211_connect_result(), WARN_ON(!bss).
Workaround this by crafting bss manually with information we can read from
device. Workaround is only used when device bss-list does not return current
bss, and so is only used with BCM4320a devices and not newer BCM4320b ones.
Fixes bug #20152.

Introduce a firmware loading state machine to manage the process
of loading firmware asynchronously and completing initialization
upon success. The state machine attempts to load the preferred
firmware image. If that fails, and if an alternative firmware
image is available, it will attempt to load that one.

The AP firmware specifies an API version in the GET_HW_SPEC
command response. Currently, the driver only supports AP
firmware for the 8366, and only supports API v1. In the future,
if higher API version firmwares emerge (possibly for different
chips), different ops can be selected based on the reported API
version.

The mwl8k can operate in AP or STA mode, depending on the
firmware image that is loaded. By default, STA firmware is
loaded. Allow the user to override this default mode at
module load time. This saves an unnecessary firmware reload
for users only interested in AP mode.
Also, the firmware image can be swapped to meet the user's
add_interface request. For example, suppose the STA
firmware is loaded, no STA interface has been added, and the
user adds an AP interface. In this case, the AP firmware
will be loaded to meet the request.

Certain firmware versions, particularly the 8388 found on the XO-1,
do not support the EHS_REMOVE_WAKEUP command that is used to disable
WOL. Sending this command to the card will return a failure that
would get propagated up the stack and cause suspend to fail.
Instead, fall back to an all-zero wakeup mask.

This hunk added by commit 66fceb69b72f seems erroneous. We don't want to
prevent suspend of the whole system if no wakeup params are set.
In the case of the usb8388 we do want to keep the card powered up even
if there are no wakeup params. This is because it will continue acting
as a mesh node.
If the mesh is disabled, it would indeed make more sense to power down
the card during suspend, as the equivalent hunk does for the SD interface.
But that's a separate task; for now just restore the previous behaviour.

macvlan is a stacked device, like tunnels. We should use the lockless
mechanism we are using in tunnels and loopback.
This patch completely removes locking in TX path.
tx stat counters are added into existing percpu stat structure, renamed
from rx_stats to pcpu_stats.
Note : this reverts commit 2c11455321f37 (macvlan: add multiqueue
capability)
Note : rx_errors converted to a 32bit counter, like tx_dropped, since
they dont need 64bit range.

Instead of unconditionally sending unassoc RXON,
before any assoc RXON, re-send only the AP STA
entry which is required after the BSSID has been
programmed into the device to set up internal

sending a lot of RXON commands to the device.

Currently, when a PAN queue needs to be
stopped, we erroneously stop queue number 5
(for example) with mac80211 -- which doesn't
even exist!
To avoid that problem, recalculate the swq_id
for all queues when setting up the queues,
and don't use the default identity mapping
that is acceptable for devices which don't
support PAN.
