iwl3945: iwl3945_mac_get_tsf() should not return zero
The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the
function is not implemented, and this is considered as a valid value by
the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc
mode is inserted/removed quite frequently due to IBSS merging.

iwlwifi: fix TX cmd dma unmapping
This patch:
1. fixes command DMA unmapping, this might be visible only
on platforms where DMA unmapping is no noop such as PPC64 (not tested)
2. attaches correctly high memory part of the host command buffer
3. changes structure of TFD TB
instead of describing transmit buffer (TB) tuple it describes single
TB and makes code more readable on price of one unaligned access
4. eliminates using of IWL_GET/SET_BITs for TFD handling
5. renames TFD structures to mach the HW spec
6. reduces iwl_tx_info size by reserving first TB to the host command

airo: Kill directly reference of netdev->priv
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.
OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.
In this driver, I don't simply use netdev_priv() to replace netdev->priv.
The reason is:
Pointer netdev->priv was changed in this driver, but it shouldn't.
Because the memory was allocated when alloc_netdev() and netdev->priv
should always point to that memory.
So I use netdev->ml_priv to replace netdev->priv.
After replacing, both ai and ai->wifidev->ml_priv point to the same memory.

about SIFS value used with 8187L: 0x22 (34) doesn't match any spec

* On 8187B, the location of EIFS register is at the same place as BRSR+1
of struct rtl818x_csr. Unfortunately there is no clean way to
accomodate 8187B differences currently, just use address of BRSR+1 and
comment about it. The same thing happens for Ack timeout register,
that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack
timeout values are in units of 4us. All these registers information
was gathered from references being the vendor gpl driver and 8180

mac80211: rewrite HT handling
The HT handling has the following deficiencies, which I've

* it always uses the AP info even if there is no AP,
hence has no chance of working as an AP
* it pretends to be HW config, but really is per-BSS
* channel sanity checking is left to the drivers
* it generally lets the driver control too much
HT enabling is still wrong with this patch if you have more than
one virtual STA mode interface, but that never happens currently.
Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
wrong, see the comment in ieee80211_enable_ht().
Additionally, this fixes a number of bugs:
* mac80211: ieee80211_set_disassoc doesn't notify the driver any

* iwl-agn-rs: always uses the HT capabilities from the wrong stuff

rfkill: rate-limit rfkill-input workqueue usage (v3)
Limit the number of "expensive" rfkill workqueue operations per second, in
order to not hog system resources too much when faced with a rogue source
of rfkill input events.
The old rfkill-input code (before it was refactored) had such a limit in
place. It used to drop new events that were past the rate limit. This
behaviour was not implemented as an anti-DoS measure, but rather as an
attempt to work around deficiencies in input device drivers which would
issue multiple KEY_FOO events too soon for a given key FOO (i.e. ones that
do not implement mechanical debouncing properly).
However, we can't really expect such issues to be worked around by every
input handler out there, and also by every userspace client of input
devices. It is the input device driver's responsability to do debouncing
instead of spamming the input layer with bogus events.
The new limiter code is focused only on anti-DoS behaviour, and tries to
not lose events (instead, it coalesces them when possible).
The transmitters are updated once every 200ms, maximum. Care is taken not
to delay a request to _enter_ rfkill transmitter Emergency Power Off (EPO)
mode.
If mistriggered (e.g. by a jiffies counter wrap), the code delays processing
*once* by 200ms.

rfkill: add master_switch_mode and EPO lock to rfkill and rfkill-input
Add of software-based sanity to rfkill and rfkill-input so that it can
reproduce what hardware-based EPO switches do, blocking all transmitters
and locking down any further attempts to unblock them until the switch is
deactivated.
rfkill-input is responsible for issuing the EPO control requests, like
before.
While an rfkill EPO is active, all transmitters are locked to one of the
BLOCKED states and all attempts to change that through the rfkill API
(userspace and kernel) will be either ignored or return -EPERM errors.
The lock will be released upon receipt of EV_SW SW_RFKILL_ALL ON by
rfkill-input, or should modular rfkill-input be unloaded.
This makes rfkill and rfkill-input extend the operation of an existing
wireless master kill switch to all wireless devices in the system, even
those that are not under hardware or firmware control.
Since the above is the expected operational behavior for the master rfkill
switch, the EPO lock functionality is not optional.
Also, extend rfkill-input to allow for three different behaviors when it
receives an EV_SW SW_RFKILL_ALL ON input event. The user can set which
behavior he wants through the master_switch_mode parameter:
master_switch_mode = 0: EV_SW SW_RFKILL_ALL ON just unlocks rfkill
controller state changes (so that the rfkill userspace and kernel APIs can
now be used to change rfkill controller states again), but doesn't change
any of their states (so they will all remain blocked). This is the safest
mode of operation, as it requires explicit operator action to re-enable a
transmitter.
master_switch_mode = 1: EV_SW SW_RFKILL_ALL ON causes rfkill-input to
attempt to restore the system to the state before the last EV_SW
SW_RFKILL_ALL OFF event, or to the default global states if no EV_SW
SW_RFKILL_ALL OFF ever happened. This is the recommended mode of
operation for laptops.
master_switch_mode = 2: tries to unblock all rfkill controllers (i.e.
enable all transmitters) when an EV_SW SW_RFKILL_ALL ON event is received.
This is the default mode of operation, as it mimics the previous behavior
of rfkill-input.
In order to implement these features in a clean way, the entire event
handling of rfkill-input was refactored into a single worker function.
Protection against input event DoS (repeatedly firing rfkill events for
rfkill-input to process) was removed during the code refactoring. It will
be added back in a future patch.
Note that with these changes, rfkill-input doesn't need to explicitly
handle any radio types for which KEY_<radio type> or SW_<radio type> events
do not exist yet.
Code to handle EV_SW SW_{WLAN,WWAN,BLUETOOTH,WIMAX,...} was added as it
might be needed in the future (and its implementation is not that obvious),
but is currently #ifdef'd out to avoid wasting resources.

"mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME"
Of course, bss_info_changed provides some more useful data.
e.g.: basic_rates, dtim_period, beacon_int and maybe even more.
Everything can be hooked up if it's necessary.

This patch fixes a typo in mac80211_hwsim.c:
use HWSIM_STA_MAGIC in hwsim_check_sta_magic() and hwsim_set_sta_magic()
instead of HWSIM_VIF_MAGIC.

iwlwifi: refactor rxon time command
This patch refactors rxon time command. It removes the usage of union tsf
in favor of u64 value and hopefully makes code more readable. There are

iwlwifi: make initial calibration set configurable
This patch adds ability to configure initial calibration set. Not all HW
supported by iwlwifi use the same calibration set, XTAL is one example.

This patch makes mac80211 handle short slot requests from the AP
properly. Also warn about uses of IEEE80211_CONF_SHORT_SLOT_TIME
