I have splitted the patch into two parts so a better review is possible 
without deciding if we put the total bandwith into nl80211 or not.

Changes since v1:
- removed noise and quality from station info in NL80211
- added bandwith to station info in NL80211
- changed name of patch file to nl80211ext_v2.patch
  
Changes since v2:
- added kernel comment lines for new fields/enums
- changed name of "bandwith" field to tx_bitrate

Changes since v3:
- added rx_bitrate to station info and sta_info
- remember bitrate of last received unicast packet to this station
- decode 802.11n MCS index for nl80211
  (maybe this should be ported to WEXT too ?)

Changes since v4:
- added tx_bitrate_flags adn tx_bitrate_mcs field to station info
- added flags for 40Mhz and small guard interval to NL80211 station info
- added mcs field to NL80211 station info

Changes since v5:
- remove rx_bitrate from patch until we get a sane way to learn the details of 
 
received 802.11n packages
-replace 802.11n bitrate arrays with calculation based on basic rates
- pushed txrate nl80211 stationinfo into nested attribute
- created station_info_rate_flags enum to save bitrate flags in station_info
- cleanup of kerneldoc

Changes since v6:
- removed mcs index to bitrate conversion
- push station info bitrate into substructure
- renamed "total" bitrate into "legacy"
- some code cleanup

Changes since v7:
- corrected a small type in nl80211 mcs representation
- splitted patch into two parts

TODO:
- tests with real 802.11n hardware
- more tests with 802.11abg hardware
