 The beacon frequency should be reduced from its current default value of
 10Hz to 1Hz.

 This will save a significant amount of airtime, see
 [http://wiki.laptop.org/go/Wireless_Management_Traffic the Wireless
 Management Traffic page] for analysis.

 Attention: This may impact current contention window adaptation logic that
 expects the beacon frequency to be 10Hz.

 Please...

    1. Marvell: please comment on the contention window adaptation logic
 impact, confirming or not that, and proposing a solution (new firmaware
 release?)
    2. Cozybit and Marvell: please clarify what is the best option to set
 the default value
