Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.
Remove all the useless code and add hooks into the

iwlwifi: reliable entering of critical temperature state
When uCode detects critical temperature it should send "card state
notification" interrupt to driver and then shut itself down to prevent
overheating. There is a race condition where uCode shuts down before it
can deliver the interrupt to driver.
Additional method provided here for driver to enter CT_KILL state based
on temperature reading.
How it works:
Method 1:
If driver receive "card state notification" interrupt from uCode; it
enters "CT_KILL" state immediately
Method 2:
If the last temperature report by Card reach Critical temperature,
driver will send "statistic notification" request to uCode to verify the
temperature reading, if driver can not get reply from uCode within
300ms, driver will enter CT_KILL state automatically.
Method 3:
If the last temperature report by Card did not reach Critical
temperature, but uCode already shut down due to critical temperature.
All the host commands send to uCode will not get process by uCode;
when command queue reach the limit, driver will check the last reported
temperature reading, if it is within pre-defined margin, enter "CT_KILL"
state immediately. In this case, when uCode ready to exit from "CT_KILL" state,
driver need to restart the adapter in order to reset all the queues and
resume normal operation.
One additional issue being address here, when system is in CT_KILL
state, both tx and rx already stopped, but driver still can send host
command to uCode, it will flood the command queue since card was not
responding; adding STATUS_CT_KILL flag to reject enqueue host commands
to uCode if it is in CT_KILL state, when uCode is ready to come out of
CT_KILL, driver will clear the STATUS_CT_KILL bit and allow enqueue the host
commands to uCode to recover from CT_KILL state.

iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000 series
When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection
mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field
in the HT Information Element to determine whether or not to use
protection.
The Operating Mode field has 4 possible settings: 0-3:
Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the
BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT
stations in a 20 MHz BSS
Mode 1: used if there are non-HT stations or APs using the primary or
secondary channels
Mode 2: if only HT stations are associated in the BSS and at least one
20 MHz HT station is associated.
Mode 3: used if one or more non-HT stations are associated in the BSS.
When in operating modes 1 or 3, and the Use_Protection field is 1 in the
Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or
CTS-to-Self.
By default, CTS-to-self is the preferred protection mechanism for less
overhead and higher throughput; but using the full RTS/CTS will better
protect the inner exchange from interference, especially in
highly-congested environment.
For 6000 series WIFI NIC, RTS/CTS protection mechanism is the
recommended choice for HT traffic based on the HW design.

iwlwifi: clarify and clean up chain settings
The chain settings we currently use in iwlwifi are
rather confusing -- and we also go by the wrong
settings entirely under certain circumstances. To
clean it up, create a new variable in the current
HT config -- single_chain_sufficient -- that tells
us whether we need more than one chain. Calculate
that based on the AP and operating mode (no IBSS
HT implemented -- so no need for multiple chains,
for station mode we use the AP's capabilities).
Additionally, since APs always send disabled SM PS
mode, keeping track of their sm_ps mode isn't very
useful -- doubly not so for our _own_ RX config
since that should depend on our, not the AP's, SM
PS mode.
Finally, document that our configuration of the
number of RX chains used is currently wrong when
in powersave (by adding a comment).
All together this removes the two remaining items
in struct iwl_ht_config that were done wrong there.
For the future, the number of RX chains and some
SM PS handshaking needs to be added to mac80211,
which then needs to tell us, and the new variable
current_ht_config.single_chain_sufficient should
also be calculated by mac80211.

atheros: add common debug printing
ath9k uses this for now, ath9k_htc is expected to re-use this
as well. We lave ath5k as is, but it certainly can also be
converted later.
The ath9k module parameter and debugfs entry is kept.

We can propagate better errors upon failed hw initialization,

atheros/ath9k: add common read/write ops and port ath9k to use it
In an effort to make hw code driver core agnostic read
and write operations are defined on the ath_common structure.
This patch adds that and makes ath9k use it. This allows
drivers like ath9k_htc to define its own read/write ops and
still rely on the same hw code. This also paves the way for
sharing code between ath9k/ath5k/ath9k_htc.

ath9k: Define bus agnostic bluetooth coex prep helper
We disable ASPM when enabling bluetooth coexistance. Disabling
ASPM is a bus specific operation. In the future other buses may
support bluetooth coexistance, an example is USB. To this end
move the current routine which disables ASPM into pci.c, and declare
it the PCI bt_coex_prep() helper. Additionally, since ASPM is
a PCI-Express primitive ensure we don't ever try to muck with ASPM
registers on non PCI-express devices.
This also cleans up hw.c to not include bus specific headers or
utilities.
