if_run release Nov. 28, 2009

What's New
* Pointers to some Rx packets were being over written before
  the packets were being passed to upper layer, and the packets
  were lost. This was also causing memory leak. This is fixed
  and no more Rx packet loss or memory leak.

* Tx rate wasn't set properly. The rate was always at the lowest.
  Now, the driver sets correct rate, and cranks up to the highest
  rate h/w supports.

* Better handling on stuffed up Tx ring. No more Tx packet drop.

* Overall, Tx rate is quite improved and driver is stable under
  heavy network traffic. So, hit it with gigantic file transferring.

* 40 more vender/device IDs have been added. Total 157 IDs.

Known Issues
* Encryption is still supported by s/w. I'm working on h/w encryption.
* "ifconfig wlan0 down" -> "ifconfig wlan0 up" now works. But, once
  "ifconfig wlan0 destroy," you still have to unplug the USB device to
  make it work again. It works fine if you are using wpa_supplicant.
* When plug in the device, it doesn't show device name properly.
