Hello.
I think there might be a bug in the following code of minstrel_ht when
deciding if RTS/CTS should be enabled:
/* enable RTS/CTS if needed:
* - if station is in dynamic SMPS (and streams > 1)
* - for fallback rates, to increase chances of getting through
*/
if (offset > 0 &&
(mi->sta->smps_mode == IEEE80211_SMPS_DYNAMIC &&
group->streams > 1)) {
ratetbl->rate[offset].count = ratetbl->rate[offset].count_rts;
flags |= IEEE80211_TX_RC_USE_RTS_CTS;
}
The code does not match what it is said in the comment. RTS/CTS is not
enabled for fallback rates when not in dynamic SMPS.
Regards.
