Hi Johannes,
Thanks for the clarification. So it seems the in the other case that you
had mentioned, we can confirm that last_tx_rate is updated with
inappropriate value.
So probably we could add another variable for the highest
performing/probability rate and update it with the txrc.reported rate
value.
The Last_tx_rate update with the highest performing/probability rate can
be removed.
As far as Last Tx Rate is concerned, should we need to check for the flag?
I think the Last Tx Rate can be updated irrespective of the
IEEE80211_HW_HAS_RATE_CONTROL set or not.
Please let me know your inputs on this.
Thanks,
Saravana

is set)?
In the other case, it's set to txrc.reported_rate upon transmission, so
it's not the *last* rate, but more accurately the highest
performing/probability rate.
