A new version of Prism2 Host AP driver was just released and it is now
available from http://hostap.epitest.fi/

2002-10-12

* added utils/hostap_diag tool for showing diagnostics information
  about wireless LAN card
  - moving debugging related code from kernel driver to user space
  - this replaces previously used
    /proc/net/hostap/wlan#/{rids,unknown_rids}
  - replaces utils/dump_mmi_dev0_status (hostap_diag -b wlan#)
* added configuration option for TX/RX antenna selection
  - prism2_param antsel_tx and antsel_rx
  - 0 = do not touch (default), 1 = use antenna diversity,
    2 = force AntSel Low, 3 = force AntSel High
* changed monitor mode configuration style
  - 'iwconfig wlan0 mode monitor' (this requires wireless tools
    versions 25 or newer) is now used to setup monitor mode
  - 'prism2_param wlan0 monitor_type <0/1>' configures which headers
    are included (0 = IEEE 802.11, 1 = Prism2 + IEEE 802.11)
  - old method 'iwpriv wlan0 monitor <2/3>' is now implemented as a
    wrapper for iwconfig mode command to provide backward compatibility
    (however, iwpriv command 'monitor' is now deprecated and it may be
    removed in the future versions)
* changed host_encrypt default in Host AP mode to be based on the
  station firmware version; f/w 1.4.9 seems to fix a bug that prevented
  firmware-based WEP encryption (although, decryption was working) to
  be used in Host AP mode; from now on, this can be configured with
  prism2_param also when using Host AP mode; the default is to use
  firmware-based encryption if f/w version is 1.4.9 or newer
* added new WDS frame options:
  - new prism2_param wds_type bitmap:
    bit0: 0 = use unicast RA/BSSID for broadcast/multicast frames to
      WDS link
      1 = use broadcast RA/BSSID for broadcast/multicast frames
          (Note! Prism2 firmware has limitations on this)
    bit1: AP client mode - if AP client mode is enabled and device is
      in Managed mode (i.e., associated to an AP), driver accepts
      4-addr WDS frames from current AP. In addition, outgoing
      frames that have a foreign source address in the Ethernet
      header are sent using 4-addr WDS frame to the AP. This allows
      station mode to perform layer 2 bridgeing. Please note, that
      due to firmware limitations Host AP in Master mode cannot
      operate with such station.
* fixed ap_bridge_packets to send broadcast/multicast packets back to
  wireless interface only in Master mode
