ac78403e14 wl1271: add workaround to avoid distortion due to excessive tx power
We still don't have proper calibration for our devices, so we are using way

d6e19d135d wl1271: workaround to send a disconnect before rejoining
We don't get any indication from the stack when we have disassociated.  In
wl1271, it is important to send a CMD_DISCONNECT before joining again,
because the firmware cleans some things up.  So we check if we're already
joined and disconnect if that's the case.

e57f14895b iwlwifi: update channel switch command API
Channel switch host command has different data structure for
different devices. Adding additional structures to support 5000 and 6000
NICs. unlike 4965, starting with 5000 series, the tx power is managed by
uCode, there is no tx power db information need to be passing from driver to
uCode; but the space needs to be reserved to match uCode expection.

1000 NIC do not support channel switch operation since it is 'bgn'
device, there is no need to have data structure defined for it.

008a9e3e3c iwl3945: move iwl_power_initialize()
iwl_power_initialize() initializes driver data (not device hardware), and does
not need to execute more than once (when the driver initializes).  Therefore, it
does not belong in iwl3945_apm_init(), which initializes hardware, and may run
more than once.

Move it to iwl3945_pci_probe(), where it will run only once.  This agrees
with similar placement in iwl-agn.c's iwl_pci_probe(), although placement
under "services" seemed more appropriate than under "mac80211".

1a34c04380 iwlwifi: fix userspace setting of sleep_level_override
The sleep_level_override debugfs file is used by the user to request a
static power index instead of the dynamic sleep values. Users are expected
to provide value from 1 to 5 as an index or -1 to disable it.

The problem at the moment is that users can also provide 0 to this file
which, together with the value 1, is translated to index 1. This is
confusing and even more so when users write 0 to sleep_level_override and
then read 1 from it afterwards.

Modify checking to treat 0 as invalid.

Now that we're unconditionally using apm_ops.stop() to reset and power-down

this bit will be set again very soon in iwl3945_hw_txq_ctx_stop() and other
following calls.

4d2ccdb948 iwlwifi: turn off device when not used.
In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user
no longer wants device active), device has not been going into low power state
via __iwl_down().  apm_ops.reset() does not put device into low power state;
instead it resets the device, then puts it into a powered-up state ready to be
re-loaded with uCode and re-started.  This has needlessly warmed up user's
laptops and drained batteries.

With current architecture in which mac80211 controls device up/down (including
resetting device after firmware errors), there is no need for apm_ops.reset()
any more; apm_ops.reset() is basically a combination of apm_ops.stop() and
apm_ops.init().

Instead, __iwl_down() now unconditionally places the device into a low-power
state via apm_ops.stop(). Device may be re-started via __iwl_up() calling
apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors),
but in the meantime, device will stop wasting energy.

Note that, even in this low power state, if driver re-enables interrupts,
the device retains the ability to sense the hardware RF-KILL switch, and
(except for 3945) interrupt the host when it changes.

f33269b896 iwl3945: update iwl3945_apm_init()
Update iwl3945_apm_init() to set up device registers in sequence most recently
recommended by factory.

Add resets for APMG interrupts and radio chip, formerly done only in
iwl3945_apm_reset(); moving them here assures that apm_init() will do
a complete job of preparing hardware not only after platform boot,
but also after apm_stop() has executed (due to rfkill, ifconfig down,
driver unload, etc.).  This is in preparation to completely remove apm_reset().

Add some comments.

9d565973de wl1271: remove unecessary qual parameter from rx status
The qual element in ieee80211_rx_status is not used anymore, so we don't need
to set it in the wl1271_rx_status() function.  This saves a bit of time in
the RX path.
