I implemented the functions:
"lpphy_update_tx_power_npt"
and
"lpphy_set_tx_power_control",

and together, both improve the bitrate of my device:


wlan0     IEEE 802.11bg  ESSID:"tommy"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: XXX 
          Bit Rate=54 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=10 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

without these patches, I maxed out at about 24 Mbit/s.
