Problem description

Update Kernel Module for Intel PRO/Wireless 3945ABG cards to version 1.2.0, changes include:
  • Workqueue rework for kernel 2.6.20 and above
  • WE-21 ESSID fix
  • Event log output enhancement
  • Fixed problem with newer kernels and config.h vs. autoconf.h
  • Fixed problem with IEEE80211 API compatibility build issues.
  • Fixed #1096 problem with soft lockup while loading if RF kill active.
  • Fixed compile warning ignoring pci_enable_device's return code.
  • Added retransmission of association and authentication requests if no response received.
  • Changed the make target install_for_testing to install.
  • Fixed #972 problem with wpa_supplicant not selecting hidden APs (Novell #177105)
  • Fixed #1113 problem with compiling against ieee80211-1.1.14
  • Fixed #1146 problem with last character of SSID being dropped.
  • Fixed #1089 circular locking dependency during register_netdev
  • Fixed #1090 problem with setting rate while not associated.
  • Fixed #1098 possible memory corruption on 64-bit systems
  • Updated README.ipw3945, ISSUES, and INSTALL to be in sync with 1.1.0.
  • Modified to not filter out legacy (non-802.11h) access points on channels marked as being in the radar detect spectrum. You must upgrade to the ipw3945d regulatory daemon version 1.7.22 or newer in order to take advantage of this functionality.
  • do not return EAGAIN and force reassociation when SSID gets cleared; this should help to fix some suspend/resume related problems (#255765)
Also update ipw3945d to version 1.7.22, required to not filer out legacy access points (non-802.11h) on channels marked as being in the radar detect spectrum.
