Both 1000 & 6000 series NICs contain on-chip OTP memory that
replaces the off-chip EEPROM memory. The nature of OTP means
there is a limited number of times a particular board can go through the
factory flow and be (re)calibrated. As a consequence there will be some boards
that contain EEPROM memory because OTP blocks were full.
In the signature validation routine, iwlwifi needs to make sure

The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
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
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.
At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.

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.

When instructing the microcode to use just a single
chain when we have power saving enabled, we should
also tell the AP that we are doing SM powersave.
However, using a single chain doesn't actually have

using one vs. two or three chains.
Therefore, always instruct the microcode to use all

The supported LED modes after this are:
IWL_LED_BLINK (current/default) - blink rate based on current Tx/Rx
traffic
IWL_LED_RF_STATE (new) -
LED OFF: No power/RF disabled, the LED is emitting no light
LED ON: Powered/RF enabled, the LED is emitting light
in a stable non-flashing state.

Current rate scale algorithm fluctuates between different MIMO modes fairly
rapidly, causing widely varying performance. These fluctuations occur because in
the rate_scale tables for expected throughput the values are not very different
for different modes.
However, when aggregation is turned on and MAC overhead is reduced, the
expected throughput for different MIMO modes grows and different modes have
vastly different performance. Add expected throughput tables for this case.
We also need to keep track of aggregation status per-station, so we add the
"is_agg" field to struct lq_sta.
Also includes cleanup of comments and variable names in/around the affected

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.

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.

specific part -- ath9k_hw_init_btcoex_hw_info(). This
highlights how ath_gen_timer is part of the driver core, not
hw related, so stuff that into ath_btcoex struct.
The ath9k_hw_btcoex_init() code is now put inline on

The address stored in the next link address is a word address but when
reading the OTP blocks, a byte address is used. Also if the blocks are
full and the last link pointer is not zero, then none of the blocks are
valid so return an error.
The algorithm is simply valid blocks have a next address and that
address's contents is zero.
Using the wrong address for the next link address gets arbitrary data,
obviously. In cases seen, the first block is considered valid when it is not.
If the block has in fact been invalidated there may be old data or
there may be no data, bad data, or partial data, there is no way of
telling. Without this patch it is possible that a device with valid OTP data
is unable to work.

Which is why I have always preferred sizeof(struct foo) over
sizeof(var).

This is based on Michal Schmidt fix for skge.
Most network drivers request their IRQ when the interface is activated.
sky2 does it in ->probe() instead, because it can work with two-port
cards where the two net_devices use the same IRQ. This works fine most
of the time, except in some situations when the interface gets renamed.
Consider this example:
1. modprobe sky2
The card is detected as eth0 and requests IRQ 17. Directory
/proc/irq/17/eth0 is created.
2. There is an udev rule which says this interface should be called
eth1, so udev renames eth0 -> eth1.
3. modprobe 8139too
The Realtek card is detected as eth0. It will be using IRQ 17 too.
4. ip link set eth0 up
Now 8139too requests IRQ 17.
The result is:
WARNING: at fs/proc/generic.c:590 proc_register ...
proc_dir_entry '17/eth0' already registered
The fix is for sky2 to name the irq based on the pci device, as is done
by some other devices DRM, infiniband, ... ie. sky2@pci:0000:00:00

...
And "ls /proc/irq/17" shows two subdirectories, both called eth0.
Fix it by using a unique name for skge's IRQ, based on the PCI address.
The naming from the example then looks like this:
$ grep skge /proc/interrupts
17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0
irqbalance daemon will have to be taught to recognize "skge@" as an
Ethernet interrupt. This will be a one-liner addition in classify.c. I
will send a patch to irqbalance if this change is accepted.
