Intel 3945 (wpi) patch

Hi,


Here is a patch for wpi(4) which should help with the stability of the
driver. If you have been having problems then please give it a try and
report back. Some people have reported problems getting wpa_supplicant
to authenticate which may not be fixed, give it a try anyway.

This includes work by Sam Leffler and Benjamin Close.


cheers,
