Tx power conttrol issue

[William Tai]

Hi All:

    I try to control my tx power on my prism2 card; however I failed.
I notice that there are 4 types of power.
 enum {
  PRISM2_TXPOWER_AUTO = 0, PRISM2_TXPOWER_OFF,
  PRISM2_TXPOWER_FIXED, PRISM2_TXPOWER_UNKNOWN
 } txpower_type;
Before I try to call prism2_ioctl_siwtxpow( ), that power type should be on
this card?
Is there any body succeed to control tx power using hostap fw and wanna
share your experience with us?


Thanx a lot
William
