Using powersave while idle saves a lot of power, but
we've had problems with this on some cards (5150 has
been reported to be problematic). However, on the new
6000 series we're seeing no problems, so for now let
that hardware benefit from idle mode, we can look at
the problems with other hardware one by one and then
enable those once we figure out the problems.

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.

Adjust led blink rate to compensate on a MAC Clock difference on every
HW. Led blink rate analysis showed an average deviation of 0% on 3945,
5% on 4965 HW and 20% on 5000 series and up.
Need to compensate on the led on/off time per HW according to the
deviation to achieve the desired led frequency
The calculation is: (100-averageDeviation)/100 * blinkTime
For code efficiency the calculation will be:
compensation = (100 - averageDeviation) * 64 / 100
NewBlinkTime = (compensation * BlinkTime) / 64

Separate set_hw_params() function for 6000
series from 5000/1000 series because:
1) 6000 series use different set of sensitivity range table
2) 6000 series has different uCode image size
Also include the new sensitivity parameters needed by sensitivity
algorithm.

Different NIC has different requirements for configuration. Currently all
5000 series hardware and later share the same configuration function even
though they do not need the same configurations. Fix this by separating the
needed configuration actions for each hardware model.
.5000 series: L1-ASPM H/W bug work-around
configure radio
write CSR_HW_IF_CONFIG_REG for uCode use
work-around for NIC get stuck after early PCIe power off
.1000 series: write CSR_HW_IF_CONFIG_REG for uCode use
setting digital SVR for 1000 card to 1.32V
.6000 series: configure radio
write CSR_HW_IF_CONFIG_REG for uCode use
write CSR_GP_DRIVER_REG to indicate radio sku

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.
This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.
Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

For 6000 series and up, additional enhanced regulatory tx power
limitation information is added to EEPROM image.
In order to setup the tx power limitation per channel correctly. Read
the enhanced tx power information from EEPROM image and update
accordingly.
The information is provided per SISO (a,b,c) chain based, it also has
information for both MIMO2 and MIMO3. For tx power regulatory
limitation, take the highest number from all the chains and update.
Also update tx_power_user_lmt to the highest power supported by any
channels and chains

Green-field mode should be configured in the HT station table. This patch uses
both the per-station GF support flag as well as the current BSS HT operation
mode (non-GF stations present flag).
Added the "ht_greenfield_support" field to struct iwl_cfg to replace the
device-specific check in rs_use_green(). That check has been moved to
iwlcore_init_ht_hw_capab().

For devices using OTP memory, EEPROM image can start from
any one of the OTP blocks. If shadow RAM is disabled, we need to
traverse link list to find the last valid block, then start the EEPROM
image reading.
If OTP is not full, the valid block is the block _before_ the last block
on the link list; the last block on the link list is the empty block
ready for next OTP refresh/update.
If OTP is full, then the last block is the valid block to be used for
configure the device.

For 6x00 2x2 NIC, two types of Power Amplifier are available.
In order for uCode to apply correct tx power,
driver needs to program the CSR_GP_DRIVER_REG register and
let uCode know the type of PA.
If driver do not program CSR_GP_DRIVER_REG register (default to 0),
then it is uCode's decision for tx power
2x2 Hybrid card: use both internal and external PA
2x2 IPA(Internal Power Amplifier) card: internal PA only

If advance thermal throttling is used the driver need to pass both
"enter" and "exit" temperature to uCode.
Using different critical temperature threshold for legacy and advance
thermal throttling management based on the type of thermal throttling
method is used except 1000.
For 1000, it use advance thermal throttling critical temperature
threshold, but with legacy thermal management implementation until ucode
has the necessary implementations in place.

Adding new API version to account for change to ucode file format. New
header includes the build number of the ucode. This build number is the
SVN revision thus allowing for exact correlation to the code that
generated it.
The header adds the build number so that older ucode images can also be
enhanced to include the build in the future.
some cleanup in iwl_read_ucode needed to ensure old header not used and
reduce unnecessary references through pointer with the data is already
in heap variable.
