Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.

Correct channel setting function must be used for AR2317.
When I tested ahb patch on bullet2 all seemed to work fine,
but it couldn't connect another host (using ibss for example).
During an analysis I observed that it's transmitting on another
channel. I looked into madwifi code and understood that
the problem is in channel setting function. So atheros RF2317 not
fully handled in the current ath5k version and must be patched.

The DMA latency issue is observed only in Intel pinetrail platforms
but in the driver we had a default PM-QOS value of 55. This caused
unnecessary power consumption and battery drain in other platforms.

Remove the pm-qos thing in the driver code and address the throughput
issue in Intel pinetrail platfroms in user space using any one of
the scripts in below links:

Commit: "p54: enhance rssi->dBm database import"
changed the way how the driver deals with the
rssical data. A new data format was necessary
and hence this patch.

NOTE: (for users with a custom eeprom binary)
I spent some time updating p54tools to support
the new format too: => (git available from)
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

It now comes with a simplistic script "n800_rssi2v2.sh"
which can be used to automate the conversion.

This patch fixes several shortcomings of the
previous implementation. Features of the
rewrite include:

 * handles undocumented "0x0000" word at the
   start of the frequency table.
   (Affected some early? DELL 1450 USB devices
    and my Symbol 5GHz miniPCI card.)

 * supports more than just one reference point
   per band. (Also needed for the Symbol card.)

 * ships with default values in case the eeprom
   data is damaged, absent or unsupported.

Writing beacon to device happen through multiple write command calls.
zd_usb_iowrite16v uses synchronous urb call and with multiple write
commands in row causes high CPU usage.

This patch makes zd_usb_iowrite16v use asynchronous urb submit within
zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing
multiple commands to device using zd_usb_iowrite16v_async. Each URB
is delayed and submitted to device by next zd_usb_iowrite16v_async
call or by call to zd_usb_iowrite16v_async_end. URBs submitted by
zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB
send by zd_usb_iowrite16v_async_end does not. This lower CPU
usage when doing writes that require multiple URBs.

zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint.
However usb_bulk_msg() internally corrects this and makes interrupt URB.

It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less
confusion.

Many users report very low speed problem on 3945 devices,
this patch fixes problem, but only for some of them.

For unknown reason, sometimes after hw scanning, device is not able
to receive frames at high rate. Since plcp health check may request
hw scan to "reset radio", performance problem start to be observable
after update kernel to .35, where plcp check was introduced.

Bug reporter confirmed that removing plcp check fixed problem for him.
