  Log:
  Add WIP support for Broadcom wireless chips:
  - STA and MONITOR operation mode are supported
  - WPA/WPA2 is supported (host based)
  - Use V3 firmware
  - 11b/g mode is supported
  
  TODOs (AKA defects ;)
  - Add the missing part of PCIe initialization (need testers)
  - Hook TX rate control support in our 802.11 layer
  - HOSTAP and IBSS operation mode support
  - Add radio tap support
  - Use V4 firmware for newer chips
  - Use firmware based crypto for V4 firmware
  - V3 and V4 firmware coexist
  - Make LED blink
  - Make my 11b only card work :]
  - Correctly configure CW and MAC level acknowledge rates based on the
    characteristic of the BSS/IBSS that we are going to join
  And blah, blah, blah ...
  
  Known to work devices, i.e. tested devices:
  o  BCM4318 (Linksys WPC54G ver.3, cardbus)
     BBP: id 0x4318, rev 0x2, pkg 2
     MAC: rev 9
     PHY: type 2, rev 7, ver 3
     RF: BCM2050, rev 8
  o  BCM4306 (Buffalo WLI2-PCI-G54S, PCI)
     BBP: id 0x4306, rev 0x3, pkg 0
     MAC: rev 5
     PHY: type 2, rev 2, ver 2
     RF: BCM2050, rev 2
  o  BCM4319 (unknown vendor, mini-PCI)
     BBP: id 0x4318, rev 0x2, pkg 2
     MAC: rev 9
     PHY: type 2, rev 7, ver 3
     RF: BCM2050, rev 8
  o  BCM4309 (unknown vendor, mini-PCI)
     BBP: id 0x4306, rev 0x3, pkg 1
     MAC: rev 5
     PHY: type 2, rev 2, ver 2
     RF: BCM2050, rev 2
  
  TX performance of above devices at different OFDM rates (unit Mbits/s):
  OFDM rate  54    48    36    24    18    12   9       6
  TX perf    23.x  21.x  18.x  14.x  11.x  8.x  4.x(1)  6.x(2)
  
  (1) BCM4319/BCM4306 listed above can only do 2.xMbits/s at 9Mbits/s
  (2) BCM4319 listed above has unstable TX performance, 4.x-6.xMbits/s,
      at 6Mbits/s
  (3) There is a bug(to be found) in driver which reverses 9Mbits/s and 6Mbits/s
  
  Thank folks at bcm-specs.sipsolutions.net for their reverse engineering work.
  Thank johill and mb on #bcm-specs IRC channel for answering my questions.
