This patch make sure we use only CCK rate for B only network.
For 3945 driver, it sets REPLY_RATE_SCALE command every time
we connect to a new network. In this command we set for every
rate the number of try and next rate. The problem mac80211 reports
same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause
using invalid rate other than CCK in B only network. THis patch
on association will examine sta valid rate on association, if no
OFDM rate in valid available rates it considers it as B only mode so
we can set REPLY_RATE_SCALE command with valid B only network and only
choose CCK rate in rate scaling.

Patch does following things
1) This patch fixes the a-band association for passive channels with new
uCode feature that it allows direct scan on passive channels after
auto-switch from passive to active. This enables sending of direct probes
on passive channels, as long as some traffic is detected on that channel.
This improves the scanning for hidden SSIDs in A-band,which is all
passive channels.
This patch fixes the bug no 1748.
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748
2) This fix will only work with uCode version 15.28.2.8 and above.
Prior versions of uCode would work only if we heard the traffic within
active dwell time, which is much shorter than passive dwell time and
is shorter than typical beacon periods. This patch also provids full
active dwell time even if we hear traffic late in passive dwell.
3) uCode API version is incremented to 2.

This adds the infrastructure to support older firmware APIs.
The API version number is stored as part of the filename, we first try to
load the most recent firmware and progressively try lower versions.
The API version is also read from the firmware self and stored as part
of the iwl_priv structure. Only firmware that is supported by driver will
be loaded. The version number read from firmware is compared
to supported versions in the driver not the API version used as part of
filename.
An example using this new infrastrucure:
if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
Driver interacts with Firmware API version >= 2.
} else {
Driver interacts with Firmware API version 1.

iwlwifi does not support AP mode in any way. For one, it doesn't even
buffer multicast/broadcast frames properly. We didn't allow zd1211rw AP
mode to be enabled without this, so iwlwifi shouldn't be allowed to
advertise AP mode either.
It also doesn't work at all, it doesn't even answer to probe requests,

This patch cleans uCode key table bit map iwl_clear_stations_table
since all stations are cleared also the key table must be.
Since the keys are not removed properly on suspend by mac80211
this may result in exhausting key table on resume leading
to memory corruption during removal
This patch also fixes a memory corruption problem reported in
http://marc.info/?l=linux-wireless&m=122641417231586&w=2 and tracked in
http://bugzilla.kernel.org/show_bug.cgi?id=12040.
When the key is removed a second time the offset is set to 255 - this
index is not valid for the ucode_key_table and corrupts the eeprom pointer
(which is 255 bits from ucode_key_table).

This enables the custom firmware regulatory solution option
on iwlwifi drivers. These devices are uncapable of mapping their
EEPROM regulatory domain to a specific ISO / IEC alpha2.
Although the new 11n devices (>= iwl 5000) have only
3 regultaory SKUs -- MOW, ABG (no N) and BG -- the older
devices (3945 and 4965) have a more complex SKU arrangement
and therefore its not practical to move this to the driver.

I asked around, and he's right, there may be platforms that do not allow
passing such such an address to the DMA API functions. This patch
changes it by using the proper dma_sync_single_range_for_cpu API
