011a03300b iwl3945 : Fix a-band association for passive channels
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.

a0987a8d68 iwlwifi: rely on API version read from firmware
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.
   }

f3f911d177 iwlwifi: fix DMA channel number in iwl_txq_ctx_stop
The patch fixes the misuse of DMA channel number by Tx queue number in
iwl_tx_ctx_stop().

The problem was originally reported by Wu Fengguang who complains
iwlagn driver takes too long time when issuing `ifconfig wlan0 down`.
The patch now decreases the interface bring down time from 2 seconds
to 0.8 second.

IV and EIV belong to eachother and don't require

With this approach we can simplify the code in
rt2x00crypto.c by using a single memcpy() when
copying the iv/eiv data. Additionally we can
move some code out of if-statements because the
if-statement would always be true.

33fd819552 iwlwifi: disable AP mode
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,
I'm guessing the packet injection code was disabled again.

6714349046 ath5k: clean up ath5k_hw_set_key
Status: O

With the addition of TKIP (and soon CCMP), key->alg is a more useful
guide to key type than the key length.

This patch cleans up key type assignment in ath5k_hw_set_key by
extracting it into its own function.  It also replaces the separate
memcpy() calls for extracting key material into the hardware format
with a loop that works regardless of key size.

Finally, the patch removes support for WEP-128 since it is a
non-standard key length that mac80211 also doesn't use.

f6bac3ea59 ath5k: preserve higher order bits when setting mac address
In some cases we would like to set the mac address without changing
the operating mode.  However, Atheros cards store PCU data in the high
16 bits of the mac address register.  Change ath5k_hw_set_lladdr() to
not clobber the PCU settings.
