Hallo Felix,
i found your patches for moving ath9k to minstrel_ht and decided to do
some testing.
For some reason, minstrel_ht exclude all HT40 rates in my network. With
native ath9k rate controller I'm able to use HT40.
Do you have any idea where to start digging?
Do the rates not even show up in the debugfs rate control stats?
correct
If so,
check the value of sta->bandwidth at the time minstrel_ht_update_caps()
is called.
hmm... for some reasons sta->bandwidth is always 0.
my rc_stats are in attachment
