b1d25a6764 rndis_wlan: increase scan timer delay
Increase scan delay from 1 sec to 6 sec. Spec says that scan by
OID_802_11_BSSID_LIST_SCAN completes in 6 seconds.
Before rfkill patch too short delay was not problem as device was
always active (radio on) and performing background scanning.

64e368bf9c b43: Implement antenna diversity support for LP-PHY
The A/G-PHY changes are fallout fixes from the enum change,
which in turn allows the LP-PHY code to be much simpler.
The antenna_to_phyctl change is a fix for a potential
existing bug that this patch may otherwise trigger.

867b2efe68 b43: Enable LP-PHY support by default and remove Kconfig warning
The most common LP-PHY device, BCM4312, is now fully functional.
So, no need to say "probably won't work for you" anymore.
It's also not "for debuggers and developers only", as it is
perfectly usable for end-users now (at least for BCM4312).

3b3ee43da4 ath5k: fix uninitialized value use in ath5k_eeprom_read_turbo_modes()
The `val' variable in ath5k_eeprom_read_turbo_modes() is used
uninitialized.  gcc 4.4.1 with -fno-inline-functions-called-once reports
it:

eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':
eeprom.c:441: warning: 'val' may be used uninitialized in this function

Comparing the code to the Atheros HAL, it's clear that the split between
ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was
incorrect.

The Atheros HAL reads both turbo and non-turbo data from EEPROM in one
function.  Some turbo mode parameters are derived from the same EEPROM
values as non-turbo parameters, just from different bits.

Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to
fix the warning.  The actual values and offsets have been cross-checked
against Atheros HAL.

1303dcfd05 iwlwifi: fix ICT irq table endianness
The ICT IRQ table is a set of __le32 values, not u32 values,
so when reading it we need to take into account that it has
to be converted to CPU endianness. This was causing a lot of
trouble on my powerpc box where various things would simply
not work for no apparent reason with 5xxx cards, but worked
with 4965 -- which doesn't use the ICT table.

68ec53292c b43: Fix and update LP-PHY code
-Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*)
 in the channel tune routines.
-Fix some typos & spec errors found by MMIO tracing.
-Optimize b43_phy_write & b43_phy_mask/set/maskset to use
 only the minimal number of MMIO accesses. (Write is possible
 using a single 32-bit MMIO write, while set/mask/maskset can
 be done in 3 16-bit MMIOs).
-Set the default channel back to 1, as the bug forcing us to use
 channel 7 is now fixed.

With this, the device comes up, scans, associates, transmits,
receives, monitors and injects on all channels - in other words,
it's fully functional. Sensitivity and TX power are still sub-optimal,
due to the lack of calibration (that's next on my list).

The problem here is that rtl8187_stop, while helding priv->conf_mutex,
runs cancel_delayed_work_sync on an workqueue that runs rtl8187_work,
which also takes priv->conf_mutex lock. Move cancel_delayed_work_sync
out of rtl8187_stop priv->conf_mutex locking region.

5bddf54962 iwlwifi: fix unloading driver while scanning
If NetworkManager is busy scanning when user
tries to unload the module, the driver can not be unloaded
because HW still scanning.

Make sure driver sends abort scan host command to uCode if it
is in the middle of scanning during driver unload.

b2ccb4dbe7 iwlwifi: fix remove key error
Fix following error by sending synchronous command and waiting for the command
to complete.

mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from hardware (-16).

-16 is EBUSY error. The asynchronous command tests for STATUS_EXIT_PENDING
while interface is getting down and it returns -EBUSY error if set.
Changing the host command from asynchronous call to synchronous call
enables command to be run while interface is going down.
