wl12xx: replace dummy_join with ROC/CROC commands
The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:
1. Allow tx/rx from the device role.
In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.
Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.
2. Keeping the antenna for a specific link.
We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).
During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.
Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.
Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.
The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control

rt2x00: Fix PCI interrupt processing race on SMP systems
When toggle_irq is called for PCI devices to disable device interrupts
it used tasklet_disable to wait for a possibly running tasklet to finish.
However, on SMP systems the tasklet might still be scheduled on another CPU.
Instead, use tasklet_kill to ensure that all scheduled tasklets are finished
before returning from toggle_irq.
Furthermore, it was possible that a tasklet reenabled its interrupt even
though interrupts have been disabled already. Fix this by checking the
DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts
during tasklet processing.
While at it also enable/kill the TBTT and PRETBTT tasklets in the
toggle_irq callback and only use tasklet_kill in stop_queue to wait
for a currently scheduled beacon update before returning.

power_save and power_restore hooks are added meaning that card drivers

the new address will be programmed when an interface gets brought up.

ath6kl: change aggreation timeout message from an error to a debug message
When I connect to my Linksys WT610N AP supporting 11n I see a lot of
aggreation timeout errors:
[ 408.885053] ath6kl: aggr timeout (st 3109 end 3140)
[ 463.872108] ath6kl: aggr timeout (st 3671 end 3702)
[ 495.010060] ath6kl: aggr timeout (st 3983 end 4014)
[ 503.604047] ath6kl: aggr timeout (st 4065 end 0)
[ 518.963047] ath6kl: aggr timeout (st 141 end 172)
[ 525.014066] ath6kl: aggr timeout (st 205 end 236)
[ 573.957051] ath6kl: aggr timeout (st 701 end 732)
[ 585.019067] ath6kl: aggr timeout (st 816 end 847)
But still the connection seems to work. To not clutter the logs change
the error message to a debug message. But add a fixme comment so that
this will be investigated.

ath6kl: remove dependency to wireless extensions
ath6kl Kconfig still had dependencies to wext, remove those as they are
not needed anymore.
Now ath6kl should not have any wext code left. Time to have a beer and
celebrate this.

ath6kl: fix crash when interface is closed but scan is ongoing
When ath6kl module was removed while a scan was ongoing the driver would
crash in ath6kl_cfg80211_scan_complete_event().
Fix the function not to iterate nodes when the scan is aborted. The nodes
are already freed when the module is being unloaded. This patch removes the
null check entirely as the wmi structure is not accessed anymore during
module unload.
Also fix a bug where the status was checked as a bitfield with '&' operator.
But it's not a bitfield, just a regular error code.
This is a port of my patch from ath6kl staging with the same title.

ath6kl: fix atomicity in ath6kl_cfg80211_scan_node()
ath6kl_cfg80211_scan_node() was calling cfg80211_inform_bss_frame()
with CFP_KERNEL but the function is executed with a spin lock taken.
This is wrong and the function must use GFP_ATOMIC instead.
