      rtl8187: Fix transmission count sent to mac80211 · 1548c86a
      Larry Finger authored
      In the commit entitled "mac80211/drivers: rewrite the rate control
      API", the meaning of the packet transmit count was changed from the
      number of retries to the total number.  In driver rtl8187, this change
      was missed.

      mac80211: Fix pid rate-setting algorithm to allow rate changes · 1dc5a841
      Larry Finger authored
      In commit 9ea2c74 named "mac80211/drivers: rewrite the rate control API",
      the meaning of status.rates[i].count was changed from number of retries
      to total number of tries. As a result, the pid rate-setting algorithm fails
      because every packet appears to have needed a retransmit.

      rt2x00: Don't switch off LED on initialization · d507748a
      Ivo van Doorn authored
      When we switch off the LEDS during initialization
      we kill rt73usb from proper functioning. The immediate
      result after the first LED command are MCU failures
      and a complete breakdown of TX/RX.

      orinoco: indicate it is using dBm in wireless_stats and spy · f941f859
      Andrey Borzenkov authored
      Since WE7 /proc/net/wireless checks whether level and noise  are in dBm
      and shows them accordingly. Indicate that we return signal and noice
      levels in dBm.

      While at it, replace raw numbers with appropriate macro.

      mac80211: make Minstrel the default rate control algorithm · 8eb41c93
      Luis R. Rodriguez authored
      This makes minstrel the default rate control algorithm
      for mac80211. For more information see:
      
      http://wireless.kernel.org/en/developers/Documentation/mac80211/RateControl/minstrel
      
      If someone can come up with a better algorithm they get a prize
