Rajkumar Manoharan 99e4d43ad5 ath9k: configure beacons based on hw opmode
Current ath9k code does not handle beacon timers on opmode
specific. One such example is that a STA beacon config overwrites
already configured AP vif's beacon timers during scan.

On multi station vif case, configure beacon timers beased
on primary vif selected. This also helps while moving back
to single STA vif from multi STA vifs, where the power save
is enabled and hw has to be reconfigured with proper
beacon and bssid/aid. Otherwise connection poll will be triggered
so frequently due to beacon loss.

Rajkumar Manoharan 4f5ef75b15 ath9k: Handle BSSID/AID for multiple interfaces
As of now bssid/aid is overridden with recently changed vif's
bss config. This may cause improper beacon updation due to
bssid/aid mismatch. On station mode, select an associated
sta vif as primary vif and configure that vif's bss into hw.
Update the primary vif on interface change and bss info change.

Jarkko Nikula 1e5f52de21 wl1251: Add support for idle mode
On Nokia N900 the wl1251 consumes the most power when the interface is up
but not associated to access point (that supports PSM). In terms of battery
current consumption, the consumption is ~180 mA higher when the interface is
up but not associated and only ~5 mA higher when associated compared to
interface down and driver not loaded cases.

This patch adds support for the mac80211 idle notifications. Chip is put into
idle very much the same way when entering into PSM by utilizing the Extreme
Low Power (ELP) mode. I.e. idle is entered by setting necessary conditions
in wl1251_ps_set_mode followed by a call to wl1251_ps_elp_sleep.

It seems it is just enough the authorize ELP mode followed by
CMD_DISCONNECT (thanks to Kalle Valo about the idea to use it).
Without disconnect command the chip remains somewhat active and stays
consuming ~20 mA. Idle mode is left by same way than PSM. The wl1251_join
call is used to revert the CMD_DISCONNECT. Without it association to AP
doesn't work when trying second time.

With this patch the interface up but not associated case the battery current
consumption is less than 1 mA higher compared to interface down case.

Jarkko Nikula a0bbb58bcb wl1251: Prepare for idle mode support
RFC for WL1251 idle mode support brought a few issues that are worth to
update before adding the idle mode support.

Since the idle mode can reuse the code that is now used in Power Save Mode
(PSM), the flag psm in struct wl1251 is changed to variable station_mode
to be able to distinguish between PSM and idle modes.

As the station mode is different than the power power save mode command
that is sent to chip, the enum wl1251_cmd_ps_mod values are used only when
communicating with the chip and new enum wl1251_station_mode values are used
inside the driver.

Confusing comment about psm and elp relation is removed since the PSM is
actually activated by putting the chip into Entreme Low Power (ELP) mode.

Felix Fietkau 5e65968a10 ath9k: fix beacon slot processing in ad-hoc mode
The recent cleanups in the beacon code fixed SWBA backoff calculation,
however it did not remove a line of code that worked around the issues
from the earlier version of the code.
After the cleanup, the initial TSF based slot calculation now always
returns 0 instead of ATH_BCBUF-1, so the previous hack that reversed the
slot order needs to be removed, as ad-hoc mode does not use staggered
beacons.

Amitkumar Karwar 2d3d0a88bd mwifiex: return success in set_default_key for WPA/WPA2
When testing wpa_supplicant with 'nl80211' driver to connect
to an AP with WPA/WPA2 security, we notice the followings:

1) add_key is called firstly with the key from cfg80211
2) set_defaut_key is called next

set_default_key() is specific to WEP keys and should not be
called in case of WPA/WPA2 security. The set_default_key()
won't be called if wpa_supplicant uses "-Dwext" option,
but it's been called if "-Dnl80211" option is specified.

We can fix this issue by adding a check to return from
set_default_key() if WEP key is not configured.

Stanislaw Gruszka 3598e1774c iwlwifi: fix enqueue hcmd race conditions
We mark command as huge by using meta->flags from other (non huge) command,
but flags can be possibly overridden, when non huge command is enqueued,
what can lead to:

WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0()
DMA-API: device driver has pending DMA allocations while released from device [count=1]

To fix introduce additional CMD_MAPPED to mark command as mapped and
serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using
hcmd_lock. Serialization will also fix possible race conditions,
because q->read_ptr, q->write_ptr are modified/used in parallel.

On the way fix whitespace.

> ath: invalid regulatory domain/country code 0x5c

It turned out that the regdomain 'APL7_FCCA' was not mapped yet.
According to Luis R. Rodriguez [Atheros' engineer] APL7 maps to
FCC_CTL and FCCA maps to FCC_CTL as well, so the attached patch
should be correct.
