It's very well possible that minstrel doesn't implement this correctly. I don't care all that much right now about minstrel, so it's up to those who do :) > Also, the code - rate_control_rate_update calls - sta_rc_update > mac80211 op. i was first thinking that i could use this for the AP side > notification to driver layer. however, a comment for sta_rc_update > indicates that it is to be used only when IEEE80211_HW_HAS_RATE_CONTROL > is true. > this led to the confusion. > > Can this op be used to update the driver about change in station's SMPS > mode for AP ? Well, in theory it could be, but it doesn't make sense. If you have a rate control algorithm in software (like minstrel) then that should likely configure the RTS, and rate control is updated via the rate control rate_update() callback instead of via the driver. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
