libertas: Improvements on automatic tx power control via SIOCSIWTXPOW.master-2008-09-11
iwconfig txpower can now be used to set tx power to fixed or auto. If set to
auto the default firmware settings are used.
The command CMD_802_11_PA_CFG is only sent to older firmware, as Dan Williams
noted the command was no longer supported in firmware V9+.
